Comp Cams Steel Retainer For 26915 & 26918 Springs Iconic Fabrication Offroad Increased compression required

Increased compression required

For 4WD models you must use King or Fox OEM replacement coil overs with 700lb springs

however the OEM case must be destroyed to extract the key

the XTR1 is built from T-slot aluminum extrusion so your setup can change as your truck build evolves

Comp Cams Steel Retainer For 26915 & 26918 Springs Iconic Fabrication Offroad Increased compression required7 Steel Retainers: 1. 055" Spring Diameter Valve springs with larger diameters require retainers to handle the higher pressures developed by the springs. New COMP Cams Steel Retainers are the perfect solution to this problem. COMP engineers used 3D CAD with FEA to design retainers with a modern and advanced contoured top profiling for lower stress, increased lift and a reduction in mass. The retainers are CNC machined to exact tolerances using CAD CAM
