These COMP Cams chromemoly steel retainers are precision machined and black-oxided, with a contoured top profile developed using 3D CAD and FEA to reduce stress and mass. Intended for 11/32" valve stems, they accommodate 1.500"–1.550" outer-diameter valve springs and handle the higher pressures of larger-diameter springs.
