7 Degree Valve Locks 5/16in

The 7 Degree Valve Locks 5/16in from COMP CAMS are precision-engineered components designed to secure valve stems in high-performance and street engine applications. These valve locks prevent unwanted valve stem movement and rotation, ensuring consistent valve train geometry and reliable engine operation across varying RPM ranges. Whether you're building a classic muscle car, restoring a street performance engine, or maintaining existing valve train components, these 7-degree locks provide the critical retention needed for predictable valve seating and longevity.

Manufactured from hardened steel with a black oxide finish, the 7 Degree Valve Locks 5/16in deliver corrosion resistance and durability in demanding engine environments. The 7-degree angle geometry is specifically designed for street and performance applications where moderate valve lift and spring pressures are present. Each set contains 16 individual locks—sufficient for a complete eight-cylinder engine—and the 5/16-inch valve stem size ensures compatibility with common domestic and import engine platforms. The black oxide coating provides both functional protection and a professional appearance on exposed valve train components.

These valve locks are ideal for engine builders, restoration specialists, and performance enthusiasts working on street-driven vehicles with standard to mild-performance camshaft profiles. Installation requires proper valve spring compressor equipment and careful attention to valve stem seating, making them suitable for both professional machine shops and experienced home builders. The standard height profile integrates seamlessly into OEM and aftermarket valve train assemblies, ensuring drop-in compatibility without clearance issues or additional machining. Proper installation of quality valve locks is essential for preventing catastrophic valve train failure and maintaining engine reliability over thousands of miles.
