Super Locks: 10° Angle, 11/32" Stem Size

These Ford four groove Steel Super LocksT feature a 10° lock angle and 11/32" valve stem size. They are recommended for all race applications because Super LocksT have a wider angle (10°) that better distributes the ever increasing valve spring loads over the retainer than typical 7° locks. Precision-machined out of super-tough, fatigue-resistant metal alloy, Super LocksT fit any COMP Cams® 10° retainer.
