11/32 Valve Lock Set

The 11/32 Valve Lock Set from Chevrolet Performance is an essential component for high-performance and stock engine builds requiring precise valve control and rocker arm stability. This set of 16 valve locks is engineered to secure valve stems and prevent unwanted valve rotation during aggressive cam profiles, high-RPM operation, and extreme engine conditions. Whether you're rebuilding a small-block or big-block Chevy, these locks are critical for maintaining valve alignment and ensuring consistent performance across your entire valve train assembly.

Manufactured from durable steel in a natural finish, the 11/32 Valve Lock Set features a 7-degree lock geometry and single-groove design optimized for 11/32-inch valve stem diameters at standard height specifications. The 7-degree angle promotes secure engagement with the valve stem groove while minimizing side load stress during valve train cycling. These locks work in tandem with valve springs and retainers to maintain proper clearance and prevent valve float, which is especially critical when running elevated boost levels, nitrous systems, or solid roller cams that demand reliable valve control.

Serious engine builders and performance mechanics rely on OEM Chevrolet Performance valve locks for rebuild accuracy and longevity in street, strip, and competition applications. The set of 16 provides complete coverage for a V8 engine configuration, ensuring uniform valve train behavior across all cylinders. Installation requires proper valve spring compressor setup and careful seating to prevent lock binding or stem damage. Compatibility is limited to Chevrolet engines designed for 11/32-inch valve stems at standard height, making verification of your engine's specifications essential before purchase.
