COMP Cams steel retainers are CNC-machined from high-grade SAE 4140 chromemoly steel and use modern contoured top profiling developed with 3D CAD and FEA to lower stress and reduce mass. They’re built for 11/32" valve stems and 1.500"–1.550" spring diameters, providing a robust solution where larger valve springs generate higher loads.
