This COMP Cams tool steel retainer is CNC‑machined with a 10 degree seating angle and built to be both light and strong. It fits engines using 1.437"–1.500" O.D. valve springs, delivering the wear characteristics and consistency expected in demanding valve train use. The retainers are engineered for durability and reliability where reduced mass and consistent performance matter in higher‑RPM or upgraded spring applications.
