Upgrade the suspension performance and off-road capability of your 2013–2018 Ram 3500 Diesel 4WD with the BDS 4 Inch Radius Arm Lift Kit featuring FOX 2.5 Performance Elite Coilover Conversion. Built for drivers who demand maximum performance, durability, and suspension travel, this system delivers improved ride quality, increased articulation, and aggressive stance while maintaining dependable on-road drivability.
The centerpiece of this system is the FOX 2.5 Performance Elite coilover conversion, which replaces the factory front suspension with race-inspired coilover shocks featuring remote reservoirs and Dual Speed Compression (DSC) adjusters. These shocks provide superior damping performance and allow drivers to fine-tune suspension response for changing terrain and driving conditions.
To improve suspension strength and geometry, the kit includes heavy-duty tubular radius arms designed to replace the factory stamped steel arms. These upgraded arms correct caster alignment while improving ground clearance and suspension articulation for demanding off-road environments.
The suspension system also includes a front adjustable track bar and sway bar correction components to maintain proper steering and suspension geometry at the lifted ride height. This ensures stable steering response, reduced bump steer, and improved overall vehicle handling.
In the rear, the system utilizes FOX 2.5 Performance Elite remote reservoir shocks designed to deliver exceptional ride control and consistent performance on rough terrain. A rear lift block system with extended U-bolts provides the proper rear lift height while maintaining towing capacity and load handling capability.
For drivers pushing their trucks harder off-road, the system offers optional FOX 2.0 hydraulic bump stops, designed to absorb heavy impacts during aggressive driving and improve suspension control during full compression events.
With clearance for up to 37-inch tires, this BDS suspension system delivers improved ground clearance, aggressive styling, and the performance needed to tackle demanding terrain while maintaining the reliability expected from BDS Suspension.
