2019-2024 Cummins BDS 4 Inch Lift Kit W/ 4-Link

Fits

Built to outperform, BDS Suspension engineered a 4-inch lift kit with 4-Link conversion for your RAM 3500 diesel-powered truck that will surely impress. 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, this lift kit includes diesel-specific Pro-Ride coil springs, heavy-duty replacement radius arms, a 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.

At this height, the transfer case needs to be indexed to allow use of the factory front driveshaft, so an indexing ring and new transmission crossmember are supplied. In the rear, this kit utilizes a high-strength fabricated lift block, heavy-duty air bag spacers, 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.
