This COMP Cams pack of 16 lightweight Tool Steel retainers fits 1.185" outside-diameter valve springs and uses a 10° seating angle to accommodate different stem sizes. CNC-machined for consistent quality and developed with FEA and CAD, the retainers are Spintron-tested for high RPM endurance. They deliver steel-level strength with substantially reduced mass compared with chromemoly retainers for race-capable valve train setups.
