This cam lock plate has a steel retaining plate and prevents the cam wheel bolts from loosening and retracting, avoiding costly engine damage. The retaining plate fits under the screw heads so that the tabs can be bent against the hexagonal surfaces, which creates a secure positive lock. Coated with a black oxide finish and complete with three screws.

Suitable for Chevrolet Small Block and Big Block engines except 1992-1996 LT1 and LT4 engines
