4 Inch Lift Kit w/ Radius Arm | Ram 3500 w/ Rear Air Ride (13-18) 4WD | Diesel

Upgrade the ride and style of your 2013-2018 RAM 3500 diesel powered truck equipped with factory rear air ride by installing 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 radius arms, 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 a high-strength fabricated lift block, heavy duty air bag spacer, longer u-bolts and a matching set of NX2 Nitro or FOX 2.0 Performance shocks.

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.

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.

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.
