RIDE HIGH WITH THIS NEW AIR RIDE COMPATABLE KIT

These new air ride compatible kits are built to the highest standard to maximize the truck's potential with room for 35" tires.

These systems have been engineered and tested to retain full functionality of the factory air ride system allowing you to adjust ride height through the various modes. Up front this 4" system includes a pair of high clearance laser cut crossmembers along with a 3-point differential relocation system and differential skid plate to create a stout subframe for the suspension components to be installed. New ductile iron CNC machined steering knuckles are supplied along with heavy duty tie rod ends to keep allow for ESC system compatibility.

The rear of the air-ride equipped RAM 1500 mimics the standard RAM 1500 with the exception of adjustable height rear air bags. The additional ride height comes from a pair of 3" top mounted air bag spacers to lift and level the stance. New air lines and fittings are supplied to along with ride height sensor brackets to maintain propoer positioning and functionality of the factory air ride system at the new height.

IMPORTANT NOTES

*IMPORTANT* Due to the complexity of your Rams factory air ride system we highly recommend using an experienced suspension specialist for installation. For help locating a specialist in your area please use our dealer locator or contact us. For information regarding the installation of this system and modifying your Ram's factory air-ride suspension check out our step by step instructions and the helpful tips video.

  1. The Rack and Pinion steering system is extremely sensitive to an out-of-round or out-of-balance tire/wheel combination. As you increase the tire diameter and/or decrease the wheel backspacing the more sensitive the system becomes and can cause minor steering wheel shimmy.
  2. It Fits factory air ride-equipped trucks only.
  3. The factory air ride is a closed-loop system. Opening the system more times than recommended in the lift instructions or factory service manual will require the system to be recharged. This can be done at any Ram dealer service department.
  4. Stock 20" wheels can be reinstalled with factory-sized tires only. Stock 17" and 18" wheels will not fit.
  5. This kit will bolt on Eco-Diesel models but it will require an aftermarket front drive shaft.
