Fabtech's 5in Coilover Conversion system allows the installation of the massive Dirt Logic 4.0 Resi Coilovers on the front of Ram 2500's and 3500's. The system utilizes the factory upper coil bucket with support gussets for superior strength. The lower mounts weld to the axle housing and have cross support gussets for the factory TracK Bar bracket. The Dirt Logic 4.0 Coilover features a stainless steel body for maximum corrosion resistance with a remote billet aluminum reservoir. These Dirt Logic 4.0's provide a super smooth highway ride with outstanding offroad damping for rough terrain. This high end system is the ultimate suspension upgrade for Fabtech's Radius Arm and 4 Link Suspensions. Estimated installation time is 4-5 hrs. Amount of holes to drill for installation - 10. Welding is required. COILOVER CONVERSION REQUIRES PREVIOUS INSTALLATION OF FABTECH RADIUS ARM OR 4 LINK SYSTEM.
