Fabtech's Coilover Conversion system is now available in a 4? lift height for use with Radius Arm and 4 Link Systems. This system utilizes the massive Dirt Logic 4.0 Coilover for a great highway ride with superior offroad capabilities. The Coilover Conversion system replaces the upper coil spring bucket with a tubular and plate style mount that reinforces the frame for rugged offroad use. The Dirt Logic 4.0 Coilover features a dual rate coil spring for a smooth ride. The stainless steel body and black NitroSteel? piston rod provide maximum corrosion resistance. The finned billet aluminum reservoir helps keep the shock cool during aggressive offroad driving. This high end Dirt Logic Coilover Conversion system is the ultimate suspension upgrade for Fabtech's Radius Arm and 4 Link Suspensions. Includes rear Dirt Logic Shocks. Estimated installation time- 7-8 hours. 6 holes to drill. No welding required. Front driveshaft modification may be required to clear exhaust on gas motor.

Our patented Radius Arms feature a full tubular structure strengthened by dimple die side plates, with an adjustable alignment cam at the axle to allow caster adjustment. Front spring lift options includes 6 replacement Coil Springs. Completing this system is a Trac Bar relocation bracket, Pitman Arm, Sway Bar drops, and a rear Block & U-bolt kit.
