Ram 1500 Ground Clearance Chart: All Years, Trims and Suspension Modes

The Ram 1500 has a ground clearance between 7.7 and 11.8 inches depending on generation, trim, and suspension type, with the TRX sitting highest at 11.8 inches. That range looks confusing because different sources measure from different points on the truck.

Some list the front axle, some list the lowest skid plate, and air suspension trucks change height on command.

This chart breaks the numbers down by generation, trim, and suspension mode, sourced from Ram’s own specification sheets. You will also find approach, departure, and breakover angle data, since those numbers matter more than raw clearance once you are actually on a trail.

How Ram Measures Ground Clearance on the 1500

Ram’s own spec sheets list ground clearance at three different points, and that is exactly why online sources disagree. Front axle clearance and rear axle clearance are measured separately, since the differential housing is usually the lowest hanging component on either end.

A third figure, listed as ground clearance with or without the skid plate, reflects the lowest point once the factory underbody protection is installed.

For most owners, the axle-measured figure is the one that matters, since a differential or skid plate scraping a rock or rut is the real-world failure point off-road. Owners on forums including 5thGenRams have run into this exact confusion,

comparing a truck’s axle clearance against a competitor’s skid-plate clearance and assuming one truck sat noticeably higher when the trucks were actually close.

With that measurement context established, here is what the 1500 actually measures by generation and trim.

Ram 1500 Ground Clearance By Generation and Trim

The table below uses axle-measured ground clearance, which Ram lists separately for the front and rear on every official spec sheet. Figures are consistent within each generation unless a specific trim changes the suspension, as noted.

The fourth-generation truck, sold from 2009 through 2018, actually sits slightly higher at the axle than the base trims of the current truck. That is a direct result of the fifth generation’s lower front-end redesign for aerodynamics, not a step backward in capability, since the base coil-spring rear axle clearance stayed close to identical across both generations.

Trucks equipped with the available air suspension work differently, since ride height is adjustable on command.

Active Level Air Suspension Ground Clearance By Mode

Trucks with the Active-Level Four Corner Air Suspension can change ground clearance by up to 4 inches across five ride-height modes. The system is available on Laramie and above, and optional on the Rebel, but it is not offered on Tradesman or Big Horn.

Normal Ride Height is the default setting for daily driving and is measured without underbody skid plates. With skid plates installed, Normal Ride Height clearance drops slightly to 8.2 inches. Aero Mode engages automatically at highway speed to improve fuel economy, while Off-Road 1 and Off-Road 2 must be selected manually and are speed limited for safety.

It is worth flagging that Ram’s original 2019 launch materials listed Off-Road 1 and Off-Road 2 slightly lower, at 9.1 and 10.1 inches. Current dealer technical documentation lists the higher 9.9 and 10.7 inch figures shown above, which likely reflects a running suspension calibration update rather than a measurement error. Either set of numbers confirms the same core point: air suspension adds close to 2 inches of usable clearance in Off-Road 2 over the standard ride height.

Ground clearance is only half the off-road picture. Approach and departure angles matter just as much on the trail.

Ram 1500 Approach Departure and Breakover Angles by Trim

Ground clearance tells you what will scrape underneath the truck. Approach and departure angles tell you what will stop you cold at the base of a ramp, ditch, or steep trail entrance.

The RHO and TRX post nearly double the approach angle of a standard 1500, which is a bigger real-world advantage on the trail than their raw clearance numbers suggest. A steep approach angle lets the front bumper clear a ledge or rock without contact, while a poor approach angle causes the bumper or front fascia to hit the obstacle before the tires even reach it.

For owners planning to run larger tires or add aftermarket protection, a 4×4-rated shock upgrade is often paired with these geometry changes to keep the ride controlled at the new height.

Why the Rebel and TRX Sit Higher Than Other Trims

The Rebel does not just look higher, it measures higher, and the reason comes down to factory-specific suspension tuning. According to owner discussion on RamForum.com, every Rebel sits 1 inch taller than a standard Ram 1500 without the Off-Road Group, using longer front and rear springs along with different shock tuning.

That 1-inch factory lift is why a coil-spring Rebel’s clearance measured at the skid plate or frame point runs close to 9.8 to 10.8 inches, even though its axle clearance is the same 8.2 inches front and 8.7 inches rear as other 4×4 trims.

The TRX takes a different approach entirely. Its ground clearance of 11.8 inches, measured with skid plate, comes from a 2-inch ride height increase over the standard 1500 combined with 35-inch tires, according to Ram’s own TRX launch specifications.

At the axle, the TRX measures 9.4 inches front and 8.0 inches rear, both higher than a standard 4×4 Ram 1500, and that figure has held consistent across every TRX model year from 2021 through 2024.

If your Ram 1500 does not have the ground clearance you need stock, a leveling or lift kit is the next step.

How Much Ground Clearance a Leveling Kit or Lift Kit Adds

A basic 2.5-inch leveling kit typically adds close to 2.5 inches of measured front clearance, based on real owner installs documented on RamForumZ, where a 2013 Ram 1500 owner confirmed a near 1-to-1 gain in front-end height after installing a ReadyLift kit. A full 4 to 6 inch lift kit goes further, correcting front and rear ride height together and allowing for larger tires that add clearance on top of the suspension gain.

Both options come with tradeoffs. A leveling kit alone can steepen the truck’s driveline angle if paired with too much lift, and any kit changes the factory alignment specs enough that a post-install alignment is required. For a fuller breakdown of kit types by year and 4WD configuration, the Ram 1500 leveling kit installation guide covers the process and real-world tradeoffs in more detail.

Getting the Right Ground Clearance for Your Ram 1500

Stock coil-spring Ram 1500 trucks sit between 7.7 and 9.2 inches at the axle depending on generation, while air suspension trucks can reach 10.7 inches in Off-Road 2 mode. The TRX tops the lineup at 11.8 inches with its factory 2-inch lift and 35-inch tires. Every one of these figures depends on where the measurement is taken, which is the real reason published numbers rarely match across different websites.

If you are planning a build around larger tires or off-road trail use, pair your ground clearance research with your truck’s payload rating, since taller suspension and bigger wheels change how your truck handles a loaded bed. The Ram 1500 payload capacity chart covers exactly that by year and configuration.

Frequently Asked Questions

What is the ground clearance of a Ram 1500?

A standard Ram 1500 measures between 7.7 and 9.2 inches of ground clearance at the axle, depending on generation and trim. Air suspension models can raise that to 10.7 inches in Off-Road 2 mode, and the TRX reaches 11.8 inches with its factory-lifted suspension.

Does the Ram 1500 air suspension increase ground clearance?

Yes. The Active-Level Four Corner Air Suspension adds up to 2 inches of clearance over Normal Ride Height when set to Off-Road 2 mode, reaching 10.7 inches total. The system also lowers the truck for easier entry and loading.

How much higher is the Ram 1500 Rebel than a regular Ram 1500?

The Rebel sits 1 inch taller than a standard 4×4 Ram 1500 without the Off-Road Group, using longer factory springs and different shock tuning. Its axle clearance still matches other 4×4 trims at 8.2 inches front and 8.7 inches rear.

What is the ground clearance of a Ram 1500 TRX?

The Ram 1500 TRX has 11.8 inches of ground clearance measured with its skid plates installed, per Ram’s official specifications. At the axle alone, the TRX measures 9.4 inches front and 8.0 inches rear.

How much ground clearance does a leveling kit add to a Ram 1500?

A typical 2.5-inch leveling kit adds close to 2.5 inches of measured front-end clearance, based on real owner installs. A full lift kit of 4 to 6 inches adds more and also allows for larger tires, which increases clearance further.
