COMP Cams Super Valve Lock 5/16in

COMP Cams is a well-known name in the performance engine parts world, and these Super Valve Locks are a prime example of their focus on race-ready components. If you're building or rebuilding an engine for serious competition, these locks are designed to keep your valve springs securely in place under demanding conditions. They feature a 10-degree lock angle and are specifically sized for a 5/16-inch valve stem, which is a common specification for many performance applications.

What sets these apart is the inclusion of a lash cap recess. This detail is important because it helps ensure the valve spring retainer sits perfectly flat, preventing any potential binding or uneven pressure that could affect valve train stability at high RPMs. This set includes 12 locks, which is typically enough for a 6-cylinder engine, and they are made from durable steel to withstand the rigors of racing.
