2019+ Ram 3500 P/U 4X4 4-Link Rear Air Suspension

4-Link Rear Air Suspension:

(Part # 10005561, Factory Leaf Spring Rear Suspension)

(Part # 10004409, Factory Rear Air Ride Suspension)

A leaf spring truck does not have to suffer through a leaf spring ride. Take your leaf springs out and trade them in for the best suspension available for a 2019 & newer Ram 3500 pickup, a Kelderman 4-Link Rear. Our suspension comes with all the components necessary to swap out the factory leaf spring suspension for a full air ride setup. This kit includes upper and lower air bag mounting plates, trailing arm mounts, adjustable trailing arms, axle clamps, industrial-strength airbags, rear cross member, adjustable panhard bar, larger rear sway bar, sway bar end links, all hardware, and a ‘manual fill’ air control kit. This setup will provide you with a great improvement in ride quality, as well as towing. Our industrial-strength airbags not only maintain your truck’s towing ability…it increases it! This is perfect if you tend to push your truck’s suspension a little beyond its limits.

Optional Air Control Systems:

The base version of this air suspension system 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.

Mechanical, Self-Leveling Air Control System (Part # SLKD2WD + HCVLK’s):

This is the most common air control system for any and all of our full air suspension products. It includes a 100% duty cycle VIAIR air compressor, a 3-gallon air tank, two mechanical height control valves, height control valve linkages, (2) dump valves, an air dryer, plus all wiring, fittings, and connections for installation. The air compressor is contained within a weather-resistant enclosure to protect the vital elements of the control system.

An in-cab control panel is provided, allowing you to control the ON/OFF power to the air compressor and a dump switch to activate the rear dump valve option. You can also use your factory auxiliary/upfitter switch panel for these two switches in place of the Kelderman control panel. This configuration allows the suspension to automatically adjust the pressure within the airbags to maintain the designed ‘ride height’ of the suspension. As soon as you hook up to a trailer, the mechanical height control valves move with the suspension’s adjustment and pull air from the onboard air tank to inflate back to the ‘ride height’ position. It will also manually bleed off air pressure when you’re unloading weight, unhooking a trailer, etc. The dump valves are designed for use with the rear air suspension and allow you to flip a switch, deflate the rear suspension down approximately 4″, and pull right out from under your trailer. The onboard air dryer removes moisture from the system periodically to prevent damage to components and remain operational in cold temperatures and climates.

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.

Adding a 2-Stage Front Air Suspension to your Ram 3500 4X4 pickup further improves your ride quality and adds even more versatility. You can add a front air suspension kit and a four-corner air control system to raise or lower the vehicle at all four corners. Regardless of what you’re looking for, Kelderman has a great option for you. With over 35+ years of experience in building air suspension systems for Ram trucks, you can count on us to transform your truck the right way.
