2016 Ram 3500 6.7 Cummins Specs 2026 Verified Specs
Quick Answer
The 2016 Ram 3500 with the 6.7L Cummins turbo-diesel produces up to 385 hp and 900 lb-ft of torque, with towing capacities exceeding 31,000 lbs depending on configuration. Key variables affecting these specs include transmission choice (68RFE vs. Aisin AS69RC), axle ratios, and gross vehicle weight ratings (GVWR). Always verify your specific truck’s capabilities using the driver-side door jamb sticker and your VIN-specific towing guide.
Owning a 2016 Ram 3500 with the 6.7L Cummins Turbo Diesel means harnessing one of the most capable workhorses ever built, but understanding its specific capabilities requires more than just a quick glance at the spec sheet. Many owners confuse different trim levels, transmission options, and axle ratios, leading to incorrect assumptions about their truck’s true towing and payload potential. In this guide, we provide verified 2016 Ram 3500 6.7 Cummins specs and the context you need to maintain, operate, and understand exactly what your truck is built to handle.

2016 Ram 3500 Performance and Drivetrain Specifications
The performance output of the 6.7L Cummins in the 2016 Ram 3500 is directly tied to the transmission installed at the factory. The engine architecture remains the same across these trims, but the powertrain control module (PCM) tune is modified to ensure drivetrain longevity based on the transmission’s torque-handling capability.
How to Verify Your Specific Truck Configuration
To determine your exact capabilities:
1. Locate the Tire and Loading Information sticker on the driver-side door jamb. This provides the true payload capacity for your specific VIN.
2. Check the Build Sheet using your VIN on the Ram official owner’s portal to confirm your rear axle ratio (e.g., 3.42, 3.73, or 4.10), which dictates GCWR.
3. Consult the Towing Guide for the 2016 model year to match your GCWR and axle ratio to the maximum trailer weight.
Understanding 2016 Ram 3500 6.7 Cummins Performance Factors
The “4th Generation” heavy-duty Ram platform was designed to offer modular performance. The inclusion of the Aisin transmission was a strategic move by Ram to bridge the gap between light-commercial and true-commercial towing needs.
Aisin AS69RC vs 68RFE: Transmission Differences
The 68RFE is the standard automatic transmission for the 2016 Ram 3500. It is well-suited for general towing but is limited to 800 lb-ft of torque. The Aisin AS69RC, a heavy-duty six-speed automatic, features a more robust gear set and torque converter, allowing the engine to safely deliver 900 lb-ft of torque.
Why Torque Ratings Vary by Configuration
Torque output is restricted primarily to protect the internal components of the transmission. Because the G56 manual transmission has different thermal and friction characteristics, it carries the lowest factory torque rating of the lineup.
2016 Ram 3500 6.7 Cummins Aftertreatment and Emissions System
Recommended Best Deal Products
The 2016 engine utilizes a sophisticated Selective Catalytic Reduction (SCR) system to meet Tier 4 emissions standards. Understanding these components is critical to avoiding costly downtime.
The 2016 6.7L Cummins requires Diesel Exhaust Fluid (DEF). Failure to replenish DEF will result in a countdown sequence that eventually restricts vehicle speed and torque, eventually forcing a “limp mode” or total engine restart prevention.

Listen Free for 30 Days- Selective Catalytic Reduction (SCR): Converts NOx emissions into nitrogen and water using DEF.
- Diesel Particulate Filter (DPF): Captures soot from the exhaust. During normal highway driving, the truck performs “passive regeneration.” If driving conditions are consistently at low speeds, “active regeneration” will occur, often indicated by an exhaust temperature warning light.
- EGR Cooler: Recirculates cooled exhaust gas to lower combustion temperatures and reduce NOx formation.
Suspension, Payload, and Towing Capability Details
The 3500 platform is distinct from the 2500 due to its rear suspension architecture, which is built for higher weight-carrying duties.
Leaf Spring Configuration for Heavy Loads
The 2016 Ram 3500 utilizes a heavy-duty leaf spring pack. In dually (DRW) configurations, these springs are further reinforced to support the massive pin weight associated with heavy fifth-wheel trailers.
Differences Between 2500 and 3500 Suspensions
While the 2016 Ram 2500 transitioned to a coil-spring rear suspension for ride comfort, the 3500 maintained the leaf spring setup to prioritize payload capacity and minimize “squat” under load. This design difference is why the 3500 is the clear choice for commercial or dedicated heavy towing.
Essential Maintenance for 2016 Ram 3500 6.7 Cummins Longevity
Recommended Best Deal Products
The High-Pressure Common Rail (HPCR) fuel system is highly efficient but unforgiving of contaminated fuel.
Replace your fuel filter/water separator every 15,000 miles. Use high-quality filters rated for the 6.7 Cummins to prevent debris from damaging injectors.
The CCV filter element must be changed at prescribed intervals (typically every 67,500 miles) to prevent internal engine pressure buildup.
2016 Ram 3500 6.7 Cummins Specs Questions Answered
What is the maximum towing capacity?
The max tow capacity varies widely, peaking at over 31,000 lbs for properly equipped dually models. You must check your specific axle ratio and GCWR.
Is the 6.7 Cummins “Bulletproof”?
With proper maintenance of the emissions system and fuel filters, it is extremely reliable. Most longevity issues stem from neglected DPF/EGR cycles or poor-quality fuel.
