4" 2019-2024 Dodge Ram 3500 4WD (w/diesel engine) Fox 2.5 Performance Elite Coilover / Radius Arm Lift Kit by BDS Suspension

The BDS 1704PES / 1705PES 4-inch Radius Arm Coilover Lift Kit transforms your RAM 3500 into a full-performance machine, engineered to handle tough trails, heavy loads, and daily driving alike. Proudly made in the USA, this system replaces the factory suspension with heavy-duty components designed for strength, control, and long-term durability.

Heavy-Duty Radius Arms

Built from high-strength tubular steel, the upgraded BDS radius arms correct caster, improve suspension geometry, and maximize ground clearance. This ensures your lifted RAM maintains proper alignment and articulation, giving you confidence both on and off the road.

FOX Coilover Conversion

The front end gets a serious performance upgrade with the BDS Coilover Conversion Kit. Mounted in the factory coil spring buckets, these FOX 2.5 Performance Elite coilovers with DSC (Dual Speed Compression) adjusters deliver a ride you can tune to perfection. Independently adjust low-speed and high-speed compression for plush comfort on the highway or firm damping on demanding terrain.

FOX Performance Elite Rear Shocks

Out back, FOX 2.5 Performance Elite shocks with DSC adjusters provide the same level of adjustability and control, keeping your truck smooth, stable, and responsive in all driving conditions. 

Optional FOX Hydraulic Bump Stops

For extreme off-road use, FOX 2.0 Factory Race Series Hydro Bump Stops can be added. These race-inspired bump stops soak up hard landings and full-travel suspension impacts, adding another layer of protection and control when driving aggressively in rough terrain.
