2014 Ram 3500 Towing Capacity: Complete Payload & Engine Guide 2026

The 2014 Ram 3500 represents a historic milestone in the heavy-duty pickup truck segment. Upon its release, this one-ton behemoth shattered industry records by achieving a maximum towing capacity of 30,000 pounds.

This achievement fundamentally altered the competitive landscape of the American truck market. It forced competitors in the ongoing “arms race” to rethink their engineering strategies.

Achieving a 30,000-pound tow rating required a comprehensive overhaul of the vehicle’s underlying architecture. Ram engineers focused heavily on the chassis, the powertrains, and the suspension systems to safely manage commercial-grade loads.

The resulting vehicle blurred the line between a traditional consumer pickup truck and a medium-duty commercial hauler. This guide meticulously unpacks the data, mechanics, and trailering science behind the 2014 Ram 3500.

Core Chassis and Structural Engineering

The foundation of any extreme towing vehicle is its frame and chassis design. The 2014 Ram 3500 utilizes a fully boxed, hydroformed frame constructed from 50-KSI high-strength steel.

This robust skeleton features eight primary cross-members designed to eliminate torsional flex under extreme load. When a 30,000-pound trailer is hitched, the frame must resist twisting forces that would otherwise compromise the vehicle’s steering geometry.

To support the immense weight over the rear wheels, the truck relies on an upgraded 11.5-inch rear axle. This heavy-duty axle housing is substantially larger than previous generations, ensuring durability during high-torque applications.

The front suspension utilizes an advanced three-link coil design to maximize roll stiffness. By mitigating body roll, this setup ensures that the heavy-duty truck maintains a planted, predictable stance even when navigating uneven terrain with a massive payload.

Powertrain Architecture: The Gasoline Engines

Selecting the correct engine is the single most critical decision for determining the 2014 Ram 3500’s towing capacity. The gasoline options provide a compelling mix of high payload limits, lower acquisition costs, and excellent everyday utility.

Gasoline engines inherently weigh less than heavy cast-iron diesel blocks. Because the engine is lighter, less of the truck’s Gross Vehicle Weight Rating (GVWR) is consumed by the powertrain itself, resulting in higher available payload capacities.

The 5.7-Liter HEMI V8

The 5.7-liter HEMI V8 serves as the standard, highly proven base engine for the 2014 Ram 3500. It produces 383 horsepower at 5,600 rpm and generates a peak torque output of 400 lb-ft at 4,000 rpm.

This legendary powerplant utilizes Variable Valve Timing (VVT) to optimize airflow and efficiency across the entire RPM range. It also features interactive Deceleration Fuel Shut-Off (iDFSO), which seamlessly halts fuel delivery when decelerating to improve efficiency.

When optimized with a 4.10 rear axle ratio, a Regular Cab model with the 5.7L V8 can tow up to 14,050 pounds. This setup provides a maximum payload capacity of roughly 4,480 pounds, making it highly capable for standard commercial hauling.

The 6.4-Liter HEMI V8

Introduced specifically for the 2014 model year, the 6.4-liter HEMI V8 was the largest displacement gasoline V8 in the heavy-duty segment at the time. It was engineered to bridge the performance gap between the base 5.7L V8 and the premium diesel option.

This engine delivers a best-in-class gasoline output of 410 horsepower at 5,600 rpm and 429 lb-ft of torque at 4,000 rpm. It was the first gasoline engine ever offered in a Ram Dual Rear Wheel (DRW) configuration, opening up new commercial possibilities.

To maximize fuel efficiency under light loads, the 6.4L V8 features Fuel Saver cylinder deactivation technology. This system essentially transforms the mighty V8 into a fuel-sipping four-cylinder when cruising down the highway with an empty bed.

Additionally, the 6.4L engine incorporates a cooled Exhaust Gas Recirculation (EGR) system, a first for a gasoline truck engine. This innovation significantly enhances engine efficiency and thermal management during heavy towing operations.

With the optimal setup, the 6.4L HEMI V8 achieves an impressive maximum towing capacity of 16,520 pounds. Furthermore, this engine unlocks the absolute highest payload rating available in the 2014 Ram 3500 lineup, reaching a staggering 7,390 pounds.

Powertrain Architecture: The Cummins Diesel

While the gasoline engines are formidable, the 6.7-liter Cummins Turbo Diesel I-6 is the undisputed king of the heavy-duty towing segment. This legendary inline-six engine is celebrated for its low-end grunt, extreme durability, and massive pulling power.

For the 2014 model year, Ram offered the Cummins diesel in three distinct output calibrations. The specific power output of the engine is entirely dependent on the transmission it is paired with.

Standard Output (Manual Transmission)

The 2014 Ram 3500 remained one of the few heavy-duty trucks to still offer a traditional manual transmission. When mated to the G56 six-speed manual, the Cummins engine is electronically governed to a standard output.

This configuration produces 350 horsepower at 2,800 rpm and 660 lb-ft of torque at 1,400 rpm. The torque is deliberately restricted to protect the manual clutch assembly from premature failure under extreme loads.

Despite the restricted torque, this purist-friendly setup still offers immense commercial capability. A manual-equipped 2014 Ram 3500 can confidently tow up to 18,510 pounds and haul a payload of 6,680 pounds.

Mid-Output (Standard Automatic)

The vast majority of diesel buyers opt for the standard automatic transmission pairing. When connected to the 68RFE six-speed automatic, the Cummins engine receives a significant bump in overall output.

This mid-output calibration generates 370 horsepower at 2,800 rpm and a massive 800 lb-ft of torque at just 1,600 rpm. The lower RPM required to hit peak torque allows the truck to pull heavy trailers up steep grades without constantly downshifting.

When properly equipped, this drivetrain combination boosts the maximum towing capacity to a highly competitive 22,550 pounds. The payload capacity for this specific setup reaches a maximum of 6,720 pounds.

High-Output (Heavy-Duty Automatic)

To achieve the class-leading 30,000-pound maximum towing capacity, buyers were required to specify the High-Output (HO) Cummins calibration. This engine is paired exclusively with the commercial-grade Aisin AS69RC transmission.

The HO Cummins produces 385 horsepower at 2,800 rpm and an earth-moving 850 lb-ft of torque at 1,700 rpm. This represented the absolute pinnacle of heavy-duty truck torque at the time of its release.

This specific powertrain configuration enables the remarkable Gross Combined Weight Rating (GCWR) of 37,600 pounds. It is the definitive choice for hotshot truckers, large equestrian transport, and massive multi-vehicle car haulers.

The Crucial Role of Transmissions

Engine power means very little if the transmission cannot efficiently transfer that rotational force to the axles. The 2014 Ram 3500 offered four highly specialized transmissions, each serving a distinct mechanical purpose.

The transmission essentially dictates the towing ceiling of the vehicle. Exceeding a transmission’s thermal or torque limits leads directly to catastrophic gear or clutch failure.

The 66RFE Six-Speed Automatic

The 66RFE is the standard six-speed automatic transmission paired with both the 5.7L and 6.4L HEMI V8 engines. It is a sophisticated, multi-range, electronically controlled unit designed specifically for gasoline powerbands.

This transmission features optimized gear ratios designed to maximize responsive performance and efficiency. It includes a driver-selectable Tow/Haul mode that alters the shift mapping, holding gears longer to maintain momentum on steep inclines.

The G56 Six-Speed Manual

The G56 six-speed manual transmission is a beloved option for traditionalists and commercial fleet operators. It features a wear-compensating clutch that maintains a consistent, like-new pedal feel over its lifetime.

The gearbox incorporates a dual-trunnion shift tower, which allows for a surprisingly compact and precise shift pattern in such a large vehicle. While it limits total torque, its mechanical simplicity offers unparalleled driver control.

The 68RFE Six-Speed Automatic

The 68RFE automatic transmission was engineered specifically to manage the immense low-end torque produced by the standard Cummins diesel engine. It is larger and more structurally rigid than the gasoline-focused 66RFE.

This unit utilizes three planetary gear sets to provide a wide overall ratio spread, enhancing both off-the-line acceleration and highway efficiency. It also features five hydraulic accumulators to ensure seamless, precise shifting regardless of the vehicle’s payload.

The Aisin AS69RC Heavy-Duty Automatic

The Aisin AS69RC is the ultimate heavy-duty transmission, mandated for the High-Output Cummins and the 30,000-pound tow rating. This commercial-grade gearbox is physically larger and significantly more robust than Chrysler’s in-house designs.

It boasts a super-low 3.75:1 first-gear ratio, providing an incredibly strong mechanical advantage when launching a 15-ton trailer from a dead stop. The transmission features wide gear ratios that drastically improve shift performance and drivability under extreme duress.

Internally, the Aisin uses a compact gear train with three clutches and two brakes, managed by an advanced shift control algorithm. The planetary components undergo a patented heat treatment process to survive the extreme thermal stresses of commercial towing.

Drivetrain Dynamics and Axle Ratios

Beyond the engine and transmission, the rear axle ratio is the final piece of the mechanical towing puzzle. The axle ratio measures the relationship between the driveshaft’s revolutions and the rear axle’s revolutions.

A higher numerical axle ratio (such as 4.10:1) means the driveshaft must turn more times to rotate the rear wheels once. This creates superior low-end torque multiplication, acting as a mechanical lever to get heavy loads moving.

Conversely, a lower numerical ratio (such as 3.42:1) prioritizes fuel economy by keeping engine RPMs lower at highway cruising speeds. However, this taller gearing sacrifices off-the-line pulling power.

The 3.42 and 3.73 Axle Ratios

The 3.42 axle ratio is standard on many diesel configurations, making it excellent for long-distance highway hauling with lighter trailers. However, trucks equipped with this ratio have significantly lower towing capacities and Gross Combined Weight Ratings.

The 3.73 axle ratio represents the perfect middle ground for many owners. It provides a balanced compromise between initial towing leverage and acceptable highway fuel efficiency.

For a driver who tows a medium-sized fifth-wheel RV on the weekends but commutes empty during the week, the 3.73 ratio keeps the engine in its optimal power band without excessive cabin noise.

The 4.10 Axle Ratio

To unlock the absolute maximum towing limits of the 2014 Ram 3500, the 4.10 axle ratio is strictly required. For gasoline engines, upgrading to the 4.10 ratio increases towing capacity by roughly 2,000 pounds.

For the High-Output Cummins diesel, the 4.10 ratio is the critical component that elevates the truck to its 30,000-pound maximum towing threshold. It provides the supreme mechanical advantage required to haul massive commercial trailers over steep mountain passes.

Cab Configurations and Weight Penalties

The 2014 Ram 3500 was available in three distinct cab configurations: the Regular Cab, the Crew Cab, and the enormous Mega Cab. The choice of cab directly impacts the vehicle’s payload and towing capacities.

The Regular Cab features an 8-foot cargo box and a short 140.5-inch wheelbase. Because this cab style uses the least amount of raw material, it has the lowest base curb weight, directly translating to the highest possible payload and towing numbers.

The Crew Cab is the standard for most buyers, offering four full-size doors and the choice of a 6-foot-4-inch or an 8-foot bed. This configuration adds significant weight to the vehicle, slightly reducing its overall towing limits compared to the Regular Cab.

The Ram-exclusive Mega Cab provides class-leading interior space and is the only heavy-duty truck cab to feature reclining rear seats. However, this massive cab style adds hundreds of pounds to the vehicle’s curb weight, establishing a “weight penalty” that lowers its maximum payload and tow ratings.

Single Rear Wheel vs. Dual Rear Wheel

The choice between a Single Rear Wheel (SRW) and a Dual Rear Wheel (DRW) setup fundamentally changes the truck’s operational dynamics. The rear wheel configuration dictates the vehicle’s maximum stability and payload ceiling.

An SRW truck is more agile in urban environments, easier to park, and provides a slightly smoother ride when the bed is empty. A properly equipped SRW model can still tow an impressive 26,080 pounds with the High-Output diesel.

However, a Dual Rear Wheel (DRW) setup—commonly referred to as a “dually”—is mandatory for extreme hauling and commercial applications. The extra set of rear tires significantly increases the truck’s rear Gross Axle Weight Rating (GAWR).

More importantly, the DRW configuration drastically widens the vehicle’s physical footprint on the road. This added width provides vital lateral stability, effectively eliminating dangerous trailer sway and resisting heavy crosswinds during high-capacity towing.

Understanding the Mathematics of Payload

Before hitching a trailer, operators must deeply understand the mathematics of payload and weight distribution. Payload capacity is a dynamic calculation, not a static number printed on a brochure.

Payload is determined by subtracting the truck’s actual curb weight from its Gross Vehicle Weight Rating (GVWR). The GVWR is the maximum legal weight the truck’s chassis can support, peaking at 14,000 pounds for 2014 Ram 3500 DRW models.

Because the Cummins diesel engine block is incredibly heavy, it consumes a large portion of the truck’s GVWR. This is the precise reason why the lighter 6.4L gasoline HEMI V8 actually boasts a higher maximum payload rating (7,390 lbs) than the diesel (6,720 lbs).

Factoring Occupants and Accessories

When calculating available payload, every single pound added to the truck must be accounted for. Manufacturer payload estimates typically assume a single 150-pound driver.

If a truck is carrying a crew of four 200-pound construction workers, that 800 pounds must be immediately subtracted from the payload rating. Additionally, aftermarket equipment like a heavy-duty fifth-wheel hitch can add over 250 pounds to the bed.

Crucially, the “pin weight” or “tongue weight” of the trailer rests directly over the truck’s rear axle, consuming payload capacity. A massive 20,000-pound fifth-wheel trailer typically applies 15% to 25% of its weight directly to the truck bed, consuming up to 5,000 pounds of payload.

Gross Combined Weight Rating (GCWR) Explained

The Gross Combined Weight Rating (GCWR) is the absolute safety threshold established by the manufacturer. It represents the maximum allowable weight of the fully loaded truck and the fully loaded trailer combined.

Exceeding the GCWR places extreme thermal and mechanical stress on the transmission, chassis, and braking system. For the 2014 Ram 3500, the GCWR varies drastically depending on the powertrain and configuration.

A base model 5.7L V8 Tradesman may possess a modest GCWR of around 18,000 pounds. In stark contrast, a properly equipped 6.7L High-Output Cummins DRW model achieves a monumental GCWR of 37,600 pounds.

To determine the true maximum trailer weight a specific truck can pull, an operator must weigh their fully loaded truck on a commercial scale. They then subtract that exact loaded truck weight from the GCWR to find the remaining allowable trailer weight.

Comprehensive Towing Hardware and Hitch Limits

The advertised 30,000-pound towing capacity cannot be achieved with a standard bumper hitch. Towing limits are strictly bound by the mechanical rating of the specific hitch hardware utilized.

Conventional Receiver Towing

Conventional towing utilizes a receiver hitch mounted beneath the rear bumper. The 2014 Ram 3500 is equipped from the factory with a robust Class V conventional receiver hitch.

A Class V hitch is categorized as commercial duty, featuring a massive 2.5-inch square receiver tube. When utilizing a specialized weight-distributing hitch system, the conventional towing limits peak between 18,000 and 20,000 pounds.

The maximum tongue weight for a Class V receiver is typically rated between 1,800 and 2,700 pounds. Exceeding this tongue weight can cause the front wheels of the tow vehicle to lift, severely compromising steering control and braking efficiency.

Fifth-Wheel and Gooseneck Systems

To safely tow loads exceeding 20,000 pounds, a fifth-wheel or gooseneck hitch system is an absolute requirement. In fact, Chrysler’s official guidelines mandate a fifth-wheel or gooseneck setup for any trailer weighing more than 12,000 pounds to maintain warranty coverage.

A gooseneck hitch utilizes a 2-5/16″ ball mounted directly to the truck’s frame, passing through a hole in the bed floor. High-end aftermarket solutions, such as the B&W Turnoverball Custom Underbed Kit, are engineered to safely manage up to 30,000 pounds of gross trailer weight.

Fifth-wheel hitches function similarly to commercial semi-trucks, utilizing a jaw-and-kingpin locking mechanism. Heavy-duty fifth-wheel units, such as the Curt PowerRide, are rated for 30,000 pounds of towing capacity and a 7,500-pound vertical load limit.

The 2014 Ram 3500 could be ordered from the factory with an integrated 5th Wheel/Gooseneck Prep Package. This system features built-in mounting “pucks” directly integrated into the frame, allowing for the rapid installation and removal of hitch hardware.

Suspension Innovations: Load Leveling Technology

Historically, heavy-duty trucks suffered from a notoriously harsh, bone-jarring ride when driven unloaded. The stiff leaf springs required to support 7,000 pounds of payload offer virtually no compliance on empty roads.

While the 2014 Ram 2500 switched entirely to a new five-link coil suspension to improve comfort, the Ram 3500 retained the traditional Hotchkiss rear leaf spring system. This decision was made to preserve the 3500’s massive, class-leading load capacities.

However, to bridge the gap between comfort and capability, Ram engineers introduced a groundbreaking supplemental rear air suspension system as an option for both SRW and DRW 3500 models.

This active system continuously monitors the vehicle’s ride height. When a high-load capacity condition exists, the onboard air compressor automatically fills the rear air bags, leveling the truck to improve stability and ride quality.

The air suspension system also includes a driver-selectable “Trailer/Tow Mode.” When activated, this mode strategically lowers the rear of the truck by approximately one inch, ensuring perfectly parallel hitch alignment and optimal trailer geometry.

Thermal Management and Active Air Systems

Pulling a 30,000-pound trailer up a steep mountain grade on a 100-degree day places unbelievable thermal stress on an engine. To mitigate this, the 2014 Ram 3500 features the industry-exclusive Ram Active Air intake system.

This intelligent system utilizes sensors to continuously monitor climate, vehicle grade, and load conditions. In normal scenarios, the system draws cool, dense air from a grille inlet to maximize horsepower and torque output.

However, during torrential rain, heavy snow packing, or water fording scenarios, the system automatically redirects the air intake path to a protected under-hood inlet. This prevents catastrophic water ingestion while ensuring the engine receives the necessary oxygen to pull heavy loads.

Furthermore, a heavily revised dual-radiator cooling system was implemented specifically for the Cummins engines. This engineering advancement resulted in a massive 25% heat reduction over previous engine generations, virtually eliminating overheating concerns during maximum capacity hauling.

Smart Exhaust Brakes and Stopping Power

Pulling 30,000 pounds uphill is an impressive feat, but safely controlling that immense mass downhill is a matter of life and death. The 6.7L Cummins engines feature a class-exclusive “Smart” Diesel Exhaust Brake system.

Also known colloquially in the trucking industry as a “Jake Brake,” this system uses the variable geometry turbocharger to create massive backpressure inside the engine cylinders.

By effectively turning the diesel engine into a massive air compressor, the system provides incredible retarding force to the drivetrain. This technology helps maintain a steady, safe downhill speed without requiring the driver to constantly ride the vehicle’s service brakes.

Utilizing the smart exhaust brake drastically reduces brake pad wear and prevents rotor warping. Most importantly, it eliminates the risk of catastrophic brake fade on steep, miles-long mountain descents, ensuring maximum safety for the operator.

Commercial Electrical Architecture and Upfits

Towing massive fifth-wheel RVs or commercial gooseneck trailers places a heavy, continuous burden on the truck’s electrical system. Trailer electronic brakes, interior RV lighting, and battery charging circuits draw significant amperage.

To address this demand, Ram offered an industry-first dual-alternator system for the 6.4L gasoline engine. This setup combines a 220-amp and a 160-amp unit, providing a massive 380-amp total output.

For the 6.7L Cummins diesel, an upgraded dual-alternator setup could generate an astounding 440 amps of peak electrical power. This ensures that system voltage never drops, maintaining perfectly consistent and safe trailer brake operation even under heavy accessory loads.

Additionally, the cabin features a dashboard-mounted auxiliary switch bank. These factory-installed, pre-wired upfitter switches allow commercial drivers to seamlessly integrate aftermarket accessories—like warning lights, air compressors, or heavy-duty winches—without cutting into the factory wiring harness.

Technology and Safety for Trailering

Modern heavy-duty towing requires advanced technological assistance to ensure safety and ease of use. The 2014 Ram 3500 features a fully integrated electronic trailer brake controller as an available option.

This controller syncs the truck’s braking input directly with the trailer’s electronic brakes. It applies proportional stopping force based on the load, ensuring smooth and safe deceleration.

The truck also boasts an available high-definition cargo-view camera. Mounted high in the center high-mount stop light (CHMSL), this camera provides a crystal-clear, top-down view of the truck bed.

This view allows drivers to perfectly align a gooseneck ball or fifth-wheel kingpin on the very first try, entirely eliminating the need for a spotter outside the vehicle. Standard Electronic Stability Control (ESC) and trailer sway control algorithms provide an additional safety net against dangerous lateral movements.

Trim Levels: Utilitarian Work to Ultimate Luxury

While the mechanical foundation remains identical across the lineup, the interior environment of the 2014 Ram 3500 ranges from a bare-bones fleet truck to a rolling luxury suite.

The Tradesman trim serves as the entry-level, utilitarian workhorse. It features easy-to-clean vinyl floors, steel wheels, and durable 40/20/40 bench seating. This trim is designed to maximize payload capacity by stripping out heavy luxury features.

The SLT trim adds essential creature comforts like power mirrors, chrome bumpers, and upgraded infotainment systems. Stepping up to the Laramie introduces premium leather upholstery, heated and ventilated front seats, and the acclaimed 8.4-inch Uconnect touchscreen interface.

At the pinnacle of the lineup sit the Laramie Longhorn and Laramie Limited trims. These models offer premium cattle tan leather, authentic real wood accents, and heated rear seats for absolute comfort.

It is vital to remember that luxury features add significant physical weight to the vehicle. A fully loaded Laramie Limited Mega Cab will have a noticeably lower payload and towing capacity compared to a stripped-down Tradesman Regular Cab, simply due to the added curb weight of the luxury components.

The Competitive Landscape in 2014

The introduction of the 2014 Ram 3500’s 30,000-pound tow rating was a direct shot across the bow of its primary competitors, Ford and General Motors. The “arms race” in the one-ton segment was intensely competitive.

In contrast, the 2013/2014 Chevrolet Silverado 3500HD equipped with the 6.6L Duramax diesel peaked at a fifth-wheel towing capacity of 23,100 pounds. The Ram’s 30,000-pound limit completely overshadowed the GM offering in purely commercial applications.

Similarly, the contemporary Ford F-350 Super Duty, equipped with the Power Stroke diesel, was an incredibly capable vehicle. However, it could not match the stratospheric 30,000-pound limit set by the Ram and its High-Output Cummins.

By utilizing the 50-KSI frame, the Aisin transmission, and the 850 lb-ft Cummins, the 2014 Ram 3500 secured an undisputed best-in-class title that would force competitors to aggressively redesign their future platforms.

People Also Ask: Critical Trailering Queries

What is the absolute maximum towing capacity of a 2014 Ram 3500?

The maximum towing capacity is 30,000 pounds. This is strictly achieved using a Regular Cab, Dual Rear Wheel (DRW), 4×2 configuration equipped with the High-Output 6.7L Cummins diesel, the Aisin AS69RC transmission, a 4.10 axle ratio, and a heavy-duty fifth-wheel or gooseneck hitch.

Can a 2014 Ram 3500 tow a large 5th wheel RV?

Yes, it is exceptionally capable of towing massive 5th wheels. Chrysler’s official towing guidelines actually require a 5th wheel or gooseneck hitch for any trailer exceeding 12,000 pounds to safely distribute the weight and maintain factory warranty coverage.

What is the difference between the 68RFE and the Aisin AS69RC transmissions?

The 68RFE is the standard Chrysler-built six-speed automatic for the diesel engine, rated to handle 800 lb-ft of torque and up to 22,550 pounds of towing. The Aisin AS69RC is a specialized, commercial-grade transmission designed specifically for the High-Output Cummins, capable of managing 850 lb-ft of torque and enabling the 30,000-pound towing limit.

Why does the gasoline 6.4L HEMI V8 have a higher payload capacity than the 6.7L Cummins?

Payload capacity is mathematically calculated by subtracting the truck’s base curb weight from its Gross Vehicle Weight Rating (GVWR). The Cummins inline-six is a massive, incredibly heavy cast-iron engine block. That extra engine weight directly subtracts from the available payload capacity, allowing the lighter gasoline HEMI to legally carry more weight in the truck bed.

Is a weight-distributing hitch required for conventional bumper-pull towing?

Yes, if the trailer weight exceeds the standard dead-weight limits of the receiver hitch. While a Class V commercial receiver can handle immense loads, a weight-distributing system is highly recommended for trailers over 5,000 pounds. It transfers tongue weight forward, preventing front-axle lift and maintaining safe, predictable steering geometry.

Actionable Conclusions for Buyers

The 2014 Ram 3500 fundamentally redefined the heavy-duty truck landscape by offering true commercial-grade towing capacities wrapped in a highly refined, civilized package. Its highly segmented powertrain strategy allows buyers to dial in the exact performance profile they require.

For buyers hauling moderate construction equipment, heavy landscaping materials, or large in-bed slide-in truck campers, the 6.4L HEMI V8 offers phenomenal value.
