These COMP Cams chromemoly steel retainers were developed using 3D CAD and FEA to deliver a contoured top profile that reduces stress, cuts mass and supports increased lift. CNC-machined to exact tolerances from high-grade SAE 4140 chromemoly and black-oxide finished, they are intended for 1.437"–1.500" spring diameters and provide reliable, positive location with COMP valve springs.
