The COMP Cams Super Valve Lock for 3/8" stems uses a wider 10° seating angle and is precision-machined from super-tough, fatigue-resistant metal alloy. Recommended for race applications, these Super Locks are intended to better distribute increasing valve spring loads over the retainer compared with typical 7° locks, improving retention under high stress.
