BDS 4 Inch Radius Arm Lift Kit w/ FOX 2.5 Ram 2500 Diesel 4WD (2014–2018)

Upgrade the stance, ride quality, and off-road capability of your 2014–2018 Ram 2500 4WD diesel truck with the BDS 4 Inch Radius Arm Lift Kit featuring FOX 2.5 Performance Elite shocks. Designed as a complete suspension system, this kit increases ground clearance and allows clearance for up to 35-inch tires while maintaining excellent handling, suspension geometry, and ride comfort.

Up front, the system uses diesel-specific Pro-Ride progressive rate coil springs engineered to provide the correct lift height with a smooth and predictable ride across varying terrain. BDS also replaces the factory stamped radius arms with heavy-duty tubular radius arms that improve strength, provide caster correction, and maintain stable suspension performance.

To correct steering geometry at the lifted ride height, the kit includes a forged drop pitman arm and heavy-duty track bar relocation bracket to help recenter the front axle and maintain proper steering alignment. Additional front suspension components include sway bar relocation hardware and brake line brackets to ensure proper function of factory systems after installation.

In the rear, the lift system uses progressive rate Pro-Ride coil springs, a rear track bar relocation bracket, bump stop extensions, and sway bar links to properly lift the truck while maintaining control and ride quality.

This system is paired with FOX 2.5 Performance Elite remote reservoir shocks with DSC adjusters, giving you premium damping control on-road and off-road. These shocks are built for high-performance use and allow suspension tuning for changing terrain, speed, and load conditions.

Engineered as a complete bolt-on suspension system, this BDS lift kit delivers improved capability, increased durability, and an aggressive stance for lifted Ram 2500 diesel trucks.
