    Manufacturer's Part Number:

    Valve locks are an often-overlooked valve train component. Regaudless of their diminutive size, Comp Cams has spent a considerable amount of time designing and testing valve locks to improve their performance and the reliability of the overall valve train. Comp Cams 10° Titanium Super Locks are not only strong and lightweight, reducing valve train mass, but incorporate a 10° ''square groove'' lock facing for premium valve holding ability.

    Comp Cams 10° Titanium Valve Super Locks must be used with 10° titanium valve spring retainers and square groove valve lock compatible valves.


    • Wider angle (10°) locks to better distribute the ever increasing valve spring loads over the retainer than typical 7° locks, reducing the chance of ''pull-through'' failure.
    • Precision machined rather than stamped for the ultimate in accuracy.
    • Super-tough, fatigue resistant alloy material.
    • Inside tang to taper relationship held tightly for repeatable valve spring installed heights.
    • Available for many popular valve sizes with & without lash cap recess.
    • Also available in +.050'' installed height versions.
    • For simplicity, any Super Lock fits any COMP Cams 10° retainer, just choose the correct lock for your valve size and application.
    • Super Locks are recommended in all race applications because of their superior strength.
