COMP Cams steel retainers are precision machined from chromemoly steel and finished in black oxide. These precision retainers are specifically designed for positive location when combined with COMP Cams high-quality valve springs. For superior strength and ultimate stability, both 7 and 10 retainers and valve locks are available.
