Overview

Raise the performance and stance of your RAM 3500 diesel with this 6-inch 4-link lift kit from BDS Suspension. Designed for trucks with rear overload leaf springs and 6-bolt transfer cases, this kit provides clearance for 37" tires while enhancing ride comfort, suspension geometry, and durability.

The 4-link conversion replaces factory stamped radius arms with high-strength tubular arms and heavy-duty brackets to improve axle control and reduce caster changes during wheel travel. Tuned Pro-Ride coil springs ensure predictable ride quality.

Steering & Driveline

The kit includes a forged drop pitman arm and track bar relocation bracket for accurate steering geometry and axle centering. The heavy-duty transmission crossmember and transfer case indexing ring adjust driveline angles to prevent vibration and allow continued use of the factory driveshaft.
