Overview

This 6-inch lift kit from BDS Suspension is designed for 2013–2018 RAM 3500 diesel-powered trucks equipped with factory rear air ride. The kit improves stance, performance, and capability while providing clearance for up to 37-inch tires. Up front, the kit includes diesel-specific Pro-Ride coil springs, radius arm drop brackets, a forged drop pitman arm, a track bar bracket for steering correction, bump stops, brake line brackets, and precision-tuned shocks. In the rear, the kit utilizes a high-strength fabricated lift block, heavy duty air bag spacers, longer U-bolts, and a matched set of shocks.

Pro-Ride Coil Springs

A pair of full-length, diesel-specific, progressive rate Pro-Ride coil springs provide the correct lift height and a smooth, predictable ride across various terrains.

Steering Correction

A forged drop pitman arm minimizes steering angle once the vehicle is lifted. Combined with a heavy duty track bar drop bracket, steering geometry is kept in phase through suspension travel while recentering the front axle.
