The BDS 5.5-Inch Radius Arm Lift Kit is a complete front lift system for 2019–2026 Ram 3500 4WD gas models with factory rear overload leaf springs, paired with FOX 2.5 Performance Elite external reservoir shocks. Heavy-duty BDS-engineered radius arms replace the factory arms — correcting caster, reducing bushing bind, and maintaining consistent geometry at 5.5-inch lift height. Gas-tuned coil springs are engineered for the Ram 3500 gas platform. Without factory rear overload leaf — order SKU 1686FPE.
