Valve Lock Set 10-Degree 8mm Steel -.050

The Valve Lock Set 10-Degree 8mm Steel -.050 from PAC Racing Springs is designed for serious engine builders and performance mechanics who require precise valve train control. These valve locks are essential components that secure the valve spring retainer to the valve stem, preventing valve float during high-RPM operation. Proper selection of valve locks is crucial for reliability and avoiding valve-to-piston contact.

This set features a 10-degree locking angle and is compatible with 8mm stem diameters, with a groove depth of -.050 inches, making it suitable for small-block applications and modern cylinder head designs. The steel construction ensures exceptional durability under high-RPM conditions while maintaining the precise geometry needed for consistent seating on the valve stem. PAC Racing Springs' manufacturing tolerances guarantee that each lock engages the retainer groove reliably, reducing wear and preventing spring collapse.

Engine builders and mechanics working with 8mm-stem valve systems will find the -.050 groove depth specification aligns with common OEM and PAC Racing Springs retainer designs. Careful attention to proper seating and gap clearance is essential during installation, and compatibility with your specific cylinder head, retainer, and valve stem should be verified before assembly.
