4 Inch Lift Kit - Ram 2500 w/ Rear Air Ride (14-18) 4WD - Gas

Important Notes

1. For OE Air Ride systems only
2. 6.4L Gas models will require exhaust modification to clear the front driveshaft and potentially the passenger's 4-link bracket.
3. 5.7L Gas models may require modification - but not in all cases.
4. The vehicle can be driven without the front driveshaft to an exhaust shop for modification and reinstalled after modification.

Improve the ride and style of your 2014-2018 RAM 2500 gas truck, equipped with factory rear air ride, with this 4-inch lift kit from BDS Suspension. Designed to improve stance, performance, and capability, this kit includes everything necessary to set your truck up right with clearance for up to 35" tires.

Up front the lift kit includes gas-specific Pro-Ride coil springs, radius arms drop brackets, forged drop pitman arm and track bar bracket for steering correction, bump stops, brake line brackets and precision tuned NX2 or FOX 2.0 nitrogen charged shocks.

In the rear this kit utilizes heavy duty air bag spacers, track bar relocation bracket to correct axle positioning, bump stop extensions, sway bar links and a matching set of NX2 Nitro or FOX 2.0 Performance shocks. BDS also supplies new air ride leveling sensor brackets to re-position the ride height sensors allowing it to perform just like it does at factory ride height and maintain full air bag range of motion.

Pro-Ride Coil Springs

A pair of full-length, gas-specific, progressive rate Pro-Ride coil springs are supplied to provide the correct lift height and smooth, predictable ride across various terrains. Manufactured from high tensile steel, our direct OE replacement coil springs are engineered with properly sized wire diameter. This results in maximum reliability without premature coil bind

Steering Correction

To optimize steering geometry once lifted, a forged drop pitman arm is used to minimize the steering angle and pair it with a heavy duty track bar drop bracket to keep them in phase through suspension travel while recentering the front axle.
