BDS 4 Inch Radius Arm Lift Kit FOX 2.0 Ram 3500 Diesel 4WD (2013–2018)

Upgrade the performance, stance, and off-road capability of your 2013–2018 Ram 3500 Diesel 4WD with the BDS 4 Inch Radius Arm Lift Kit featuring FOX 2.0 Performance Series shocks. Engineered for durability and precision suspension geometry, this lift kit provides increased ground clearance, improved ride quality, and the strength needed for demanding work or off-road adventures.

The front suspension system includes diesel-specific Pro-Ride coil springs designed to deliver the correct lift height while maintaining smooth and predictable ride characteristics across a wide range of driving conditions. These progressive rate springs are paired with heavy-duty tubular radius arms, which replace the factory stamped steel arms to improve strength, handling stability, and caster control.

To maintain proper steering geometry at the lifted ride height, BDS includes a forged drop pitman arm and heavy-duty track bar relocation bracket. These components work together to correct steering angles and keep the front axle centered throughout suspension travel, improving both on-road handling and off-road performance.

In the rear, the system utilizes a high-strength fabricated lift block and extended u-bolts to provide balanced lift while maintaining factory load capacity and towing capability. FOX 2.0 Performance Series shocks complete the suspension upgrade, delivering responsive damping, improved control, and enhanced ride comfort both on the highway and over rough terrain.

Designed as a complete bolt-on suspension upgrade, the BDS 4 Inch Radius Arm Lift Kit allows your Ram 3500 to run larger tires while improving overall suspension performance, durability, and capability.
