2025+ RAM 2500 4X4 Pickup 3″ Front & Rear Air Suspension Lift Kit

This kit gives your RAM 2500 the smooth ride, towing ability, and adjustable height that Kelderman has delivered to the lift kit market for 25+ years. This listing is for a combined front and rear air suspension lift kit, compatible with RAM 2500 trucks equipped with either factory rear coil springs or factory rear air suspension. Front-only or rear-only systems are also available. This kit will have a designed ride height of a 3″ lift for traveling down the road. It is adjustable down to approximately 1″ below stock height when deflated and up to an approximate 6″ lift when fully inflated. 35″ tires are recommended.

3″ Front Lift Kit

(Part # 10034769)

Our 3″ Front Air Suspension Lift Kit consists of upper and lower airbag mounting plates, industrial-strength airbags, shock mounts, dual steering stabilizer bracket, radius arm crossmember drop bracket, and an adjustable track bar. All air suspension systems include a ‘manual fill’ air control package with air line and Schrader valves to inflate the suspension to the designed 3″ ‘ride height’. Optional air control systems such as the Air Lift ALP4 Electronic Control System provide you the flexibility to adjust the truck from the 3″ ‘ride height’ down to approximately stock height when ‘deflated’ and up to nearly a 7″ lift kit when the bags are ‘maxed out’!

Fabricated Radius Arm Upgrade

(Part # 10045536)

Made with high-quality materials and precise engineering, the Kelderman fabricated radius arm upgrade is included with the 2025+ RAM 2500 3″ Air Suspension Lift Kit. These radius arms feature an improved appearance over the factory arms, as well as adjustable caster bolts to aid in front-end alignment. They provide you with an excellent place for accent colors for a unique touch on your suspension.

Dual Steering Stabilizer Assembly

(Part # 10038633)

A dual steering stabilizer bracket can make a big difference in how your truck drives down the road. Upgrade the steering and handling of your truck with Kelderman’s dual steering stabilizer bracket. This setup comes complete with all the necessary steel brackets and hardware for installation.

Rear Air Suspension Kit

(Part # D4R4-2-X-14-3)

Designed for RAM 2500 trucks equipped with either factory rear coil springs or factory rear air suspension, the Kelderman 4-Link Rear Air Suspension replaces the factory rear suspension components with a fully adjustable air suspension system.

Your Ram isn’t your only toy, right? You’ve got stuff that you put in the back of this thing and don’t want it to squat under a load. With a Kelderman Air Suspension System, you are able to add additional air pressure to the suspension and level out the truck with the push of a button (air controls required). What’s the point in having a truck that has its headlights pointed at the sky as soon as you hook up to your trailer? Get rid of all your trouble towing with a Kelderman Air Suspension System. This 3″ Lift Kit should allow you to pull most gooseneck and fifth-wheel trailers too! 35″ tires are recommended for this suspension.

The rear air suspension kit includes upper and lower airbag mounts, industrial-strength airbags, adjustable trailing arms, trailing arm mounts, adjustable panhard bar with heim ends, panhard bar mount, brake line relocation bracket, upgraded rear sway bar, sway bar end links, and sway bar end link mounts.

NOTE: The base price includes the 3″ Front Air Suspension and the 3″ 4-Link Rear Air Suspension. Air control systems, shock packages, and other options are add-ons to the lift kit package. Front-only and rear-only air suspension systems are also available.

Optional Air Control Systems:

The base version of these front and rear air suspension systems will be in a ‘manual fill’ package. This provides you with the necessary amount of air line, fittings, and Schrader valves to inflate and deflate the suspension like you would a tire. Several air control systems are available, so let’s go through some popular options.

Air Lift ALP4 Electronic Air Control System (Part # 10040870)

Are you looking for maximum control over your air suspension? In addition to its self-leveling abilities, this electronic air control system allows you to manually adjust the suspension at all four corners. The in-cab controller offers programmable preset positions and manual control over the entire suspension system. Dual VIAIR air compressors and dual 3-gallon air tanks provide the air supply necessary to raise & lower the truck. The ALP4 system also has Bluetooth connectivity and lets you see the in-cab control screen right on your phone. You can wirelessly connect to the truck suspension and control everything with the touch of a button, inside or outside of the truck. Using the controller or app, you can drop the suspension from the 2-3″ ride height setting down to 1″ below factory height or raise it to a 6″ lift when fully inflated. This makes it easier for you to enter or exit the truck, park in a low-clearance garage, go through your favorite car wash/drive-thru, and make hooking up to your trailers a breeze!

With great functionality also comes great reliability. This air control system features a combination of parts that Kelderman has trusted for years in a variety of air suspension applications. Ride height sensors provide feedback to the control system to maintain the proper ride height for correct suspension travel, load leveling, and optimum ride quality. The onboard air dryer removes moisture from the system and is operated with its in-cab purge button. Purging moisture from the control system periodically will prevent damage to the components and keep you functioning in cold weather. The ALP4 Air Control System features a steel compressor box enclosure to house the air compressors and a number of other electronic components in a weather-resistant area to protect it from road debris and weather and to reduce overall noise. This is the most common air control choice for our lift kit applications.

Mechanical, Self-Leveling Air Control System – Dual Compressor & Tank (Part # 30664 + HCVLK’s)

Want more air for your air suspension? This air control system is identical to the system referenced above, but with an additional air compressor and air tank. We tend to see this more with serious work truck applications, fleet use, trucks running at MAX GVWR, or those that plan to regularly raise & lower the rear air suspension. The additional air compressor and tank provide a quicker recovery time and make sure plenty of air is available for raising & lowering the suspension and any necessary ride height adjustments.
