Built to outperform, BDS Suspension engineered a 6-inch lift kit with 4-Link conversion for your 2013-2018 RAM 3500 diesel powered truck that will surely impress.

Up front the lift kit includes diesel-specific Pro-Ride coil springs, 4-Link control arms with conversion mounts, 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, longer u-bolts and a matching set of NX2 Nitro or FOX 2.0 Performance shocks.

4-Link Conversion

Convert the factory stamped steel radius arms over to the BDS 4-link to optimize suspension geometry for better handling characteristics while adding strength and stability. This bolt-on upgrade utilizes high-strength 1/4-inch steel brackets that allow mounting of HD upper and lower control arms to correct axle positioning while limiting caster change throughout wheel travel.

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.

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.
