The COMP Cams Super Valve Lock for 3/8" stems is a 10° retainment lock intended for demanding valve spring loads. Precision machined from fatigue-resistant metal alloy, the wider 10° angle helps distribute spring forces more evenly than typical 7° locks. This Steel Super Lock includes a lash cap recess and is specified with a .050" install height for compatibility with COMP Cams 10° retainers.
