4 Inch Lift Kit w/ Radius Arm | Ram 2500 w/ Rear Air Ride (14-18) 4WD | Diesel - FOX 2.0 Performance Series

Take your 2014-2018 RAM 2500 diesel powered truck, equipped with factory rear air ride, to the next level with this 4-inch radius arm 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 diesel-specific Pro-Ride coil springs, heavy-duty replacement radius arms, forged drop pitman arm and track bar bracket for steering correction, sway bar relocation, 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.

HD Radius Arms

In place of the factory stamped steel radius arms BDS supplies a pair of high-strength tubular radius arms. These arms mount into the factory location and offer caster adjustment for a wide range of lift heights along with an OE-style rubber bushing at the frame mount for smooth, quiet, service-free operation.

Pro-Ride Coil Springs

A pair of full-length, diesel-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.
