Valve Locks - 7 Degree +.050

The Valve Locks - 7 Degree +.050 from Crower are precision-engineered retention components designed for high-performance engine builds where valve control and reliability are non-negotiable. These locks are essential for any serious engine builder or racer running aggressive cam profiles, whether you're assembling a street performance engine, track-focused build, or competition platform.

By securing the valve spring collar to the valve stem, valve locks prevent unwanted valve movement during extreme operating conditions—preventing costly failures and catastrophic engine damage that can result from valve float or spring surge at high RPM. The 7-degree angle and +.050 oversize specification indicate these locks are tailored for engines requiring upgraded valve stem geometry or custom valve train configurations common in modified powerplants.

Manufactured to Crower's exacting standards, these locks deliver consistent performance across thousands of engine cycles, maintaining their grip on the valve stem even as temperatures cycle and engine vibration increases—critical when running higher-than-stock valve spring pressures or extended RPM limits. Valve Locks - 7 Degree +.050 are ideal for engine builders, performance shops, and enthusiasts upgrading cylinder heads or installing custom valve train setups.
