COMP Cams Super Valve Locks for Chrysler use a 10° retainer angle and are sized for 3/8" valve stems. Precision-machined from fatigue-resistant metal alloy, these two-groove Super Locks are recommended for race applications because the wider 10° geometry spreads spring loads over the retainer more effectively than standard 7° locks, improving retention under high spring loads.
