Ram HD Radius Arm Box Kit 2-6" Lift (BDS122321)

BDS heavy-duty radius arm box kit for 2014-2025 Ram 2500 and 2013-2023 Ram 3500 running 2" to 6" of lift. It replaces the weak factory stamped arms with 1-3/4" OD heavy wall tubing, fully gusseted and welded, to correct suspension geometry and add tire and ground clearance over drop brackets. Larger OE-style rubber bushings isolate noise and vibration with zero maintenance, and lower cam slots make caster adjustment easy. Direct bolt-in fit.
