COMP Cams Super Valve Locks Eb +.050 - Set of 100

If you're building a high-performance or race engine, COMP Cams Super Valve Locks are a solid choice for keeping your valvetrain secure. These are a set of 100 single groove locks, designed for 3/8 inch valve stems and are +.050 inches in height. They are precision machined, not stamped, from a fatigue-resistant alloy material, which helps them hold up under the intense demands of racing.

What sets these apart is the 10-degree angle on the lock. Unlike more common 7-degree locks, this wider angle helps distribute the increasing spring loads across the retainer more effectively. This design significantly reduces the chance of a "pull-through" failure, a critical concern in high-load applications where stock parts might not hold up. Because they are machined, you can expect consistent accuracy and a reliable fit with your valve retainers.
