Comp Cams Mustang GT/Cobra/5.0L Valve Keepers (1979-1995)

These COMP Cam single groove Steel Street Lock are the perfect replacement locks for stock engine rebuilds. It's recommended that these are only for street applications with lighter valve spring loads.

Note: Valve locks must match the valve size. There should be a small gap between the two halves of the lock when they are properly positioned on the valve stem.
