2010-2013 Ram 2500/3500 4X4 Pickup 4-Link Rear Air Suspension

4-Link Rear Air Suspension:

(Part # D4R4-23-X-10)

Are you looking for a better ride AND better towing? That is exactly what a Kelderman 4-Link Rear Air Suspension provides. This kit gives you the best of both worlds by eliminating your factory leaf spring suspension and upgrading your Super Duty to a durable 4-Link Rear Air Suspension System. This kit includes upper and lower air bag mounting plates, industrial-strength air bags, trailing arm mounts, adjustable trailing arms, axle clamps, rear crossmember, adjustable panhard bar, upgraded rear sway bar, sway bar end links, all required hardware, air line, fittings, and Schrader valve style inflators.

The result of a 4-Link Rear Air Suspension on your Ram truck is a dramatic change in ride quality with an increase in towing abilities. The industrial air bags found in our 4-Link Rear kits are similar to what you would see in a semi-truck application. They are rated to carry more weight than your existing leaf spring suspension to make sure you can tow or haul whatever your truck needs to do.

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)

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.

You deserve a truck with suspension that can do it all. Don’t settle for a heavy-duty ride just because you need a heavy-duty truck. Upgrade your springs to a Kelderman 4-Link Rear Air Suspension today!
