Fits

Completely revamp your Cummins with the BDS Suspension 6" 4-Link Suspension System. The latest suspension system option to come from BDS is a complete conversion system for the new radius arm suspension on the Ram 3500. The design starts with 2 massive frame brackets that provide the mounting points for the new upper and lower control arms. These brackets locate off of the factory radius arm brackets, no factory bracket removal is required, this provides a more controlled steering feel in any terrain and better suspension geometry with reduced caster change through wheel travel.
