3" 2013-2018 Dodge Ram 3500 4WD (w/diesel engine) Fox 2.5 Performance Elite Coilover / Radius Arm Lift Kit by BDS Suspension

Engineered for serious strength and off-road performance, the BDS 1622PES 3" Radius Arm Lift Kit for RAM 3500 delivers the ideal blend of capability and durability. This system replaces the weak factory components with heavy-duty tubular radius arms that improve articulation, correct caster, and maximize ground clearance—ready for everything from rocky trails to daily driving.

Up front, the kit pairs with the BDS Coilover Conversion System using FOX 2.5 Performance Elite coilovers with DSC (Dual Speed Compression) adjusters for easy, on-shock tuning of low- and high-speed compression—letting you dial ride quality, body control, and bottom-out resistance to your preference. In the rear, FOX 2.5 Performance Elite shocks with DSC adjusters keep your truck composed and smooth whether you’re towing, hauling, or exploring off the beaten path.

For drivers who push harder, the optional FOX 2.0 Hydraulic Bump Stops add a final layer of impact control when using full suspension travel. Whether you’re crawling rocks, blasting desert whoops, or turning heads in town, this kit delivers confidence, control, and long-term durability.

Bump Stop Options

Rubber Bump Stops

Factory-style rubber stops act as a hard limit to protect shocks and other components. Ideal for street use and light off-roading where impacts occur at lower speeds.

FOX 2.0 Factory Race Series Hydraulic Bump Stops

Designed for aggressive off-road use, these hydraulic bump stops deliver superior impact absorption at full suspension travel. Perfect for drivers who tackle high-speed terrain and big obstacles while maintaining comfort and control.
