11/32 Valve Locks - -.050 Installed Height

The 11/32 Valve Locks – .050 Installed Height by Edelbrock are precision-engineered components designed to secure valve stems in high-performance and racing engine builds. These valve locks are essential for engines running aggressive cam profiles, elevated RPM ranges, or modified valve train configurations where standard locks may allow unintended valve stem movement. Whether you're assembling a competition small-block or building a street performance engine, these locks provide the retention reliability required for consistent operation and longevity.

Each set includes 16 valve locks manufactured from hardened steel in natural finish, compatible with 11/32 inch valve stems and engineered with a 7-degree locking angle for optimal grip and retention. The .050 inch reduction in installed height allows tuners to fine-tune valve lash and spring pressures without requiring additional shim modifications, making them ideal for custom cylinder head porting or when optimizing valve train geometry. The steel construction and precise 1.75 inch outer diameter ensure durability across sustained high-RPM applications and thermal cycling common in race and performance environments.

Engine builders, performance shops, and serious enthusiasts benefit most from these valve locks when upgrading stock valve train components or replacing worn locks in rebuilt heads. Installation is straightforward—the locks seat onto the valve stem grooves with the keyed design ensuring proper orientation and consistent seating across all 16 pieces. Compatible with any engine platform using 11/32 valve stems, these locks are particularly valuable in Chevy small-block, big-block, LS-series, and aftermarket head applications where precision engineering and repeatability are non-negotiable.
