The COMP Cams Titanium Super Lock is a precision titanium lock for 5/16" valve stems with a 10° retainer angle and a lash cap recess. Made for race applications, the wider 10° angle helps distribute increasing valve spring loads across the retainer. Use these when a 5/16" stem and 10° retainers are specified and verify proper lock-to-stem gap for secure fitment.
