11/32in 10Deg Super Locks W/Lash Cap Recess

The Comp Cams 11/32-inch 10-degree Super Locks with lash cap recess are precision valve lock components engineered for high-performance engine builds. These locks secure valve springs to the valve stem with a tight mechanical fit, preventing spring collapse during high-RPM operation. Designed for use with 11/32-inch valve stems, the 10-degree angular design ensures proper load distribution across the valve lock seat, reducing stress concentration and extending component life in forced-induction and competition applications.

Machined from heat-treated steel with black oxide finish, these locks deliver corrosion resistance and durability in harsh engine environments. The lash cap recess geometry accommodates valve lash adjustment shims while maintaining spring preload integrity. Each set includes 16 locks—sufficient for an eight-cylinder engine (two locks per valve). The black oxide coating protects against rust and oxidation while reducing reflectivity, which is standard for competition valve train components. The set format allows builders to replace worn or damaged locks as a matched unit, ensuring consistent valve train geometry across all cylinders.

These locks are suited for engine builders, performance enthusiasts, and machine shops assembling competition heads, stroker motors, and aftermarket cylinder heads. Super Locks are commonly specified for oval-track racing, drag racing, road racing, and street performance applications where valve train reliability is non-negotiable. Installation requires proper valve spring assembly techniques and spring pressure verification to ensure optimal clamping force and long-term reliability.

Comp Cams is recognized in the performance automotive industry for precision valve train components. The 10-degree lock angle is a standard design feature for most modern domestic and import cylinder head applications. Verify stem diameter and lock angle compatibility with your cylinder head and valve supplier before ordering. When paired with quality valve springs and retainers, these locks provide the security and durability required for sustained high-RPM operation.
