Super 7 Valve Locks - .050in

The Super 7 Valve Locks - .050in are essential components for high-performance engine builders looking to achieve precise valvetrain geometry. These specialized locks are designed for use with 0.341-inch valve stems, providing a secure interface between the valve and the spring retainer. Whether you are performing a custom head build or upgrading an existing assembly, these locks ensure stability under high RPM conditions. Many enthusiasts buy these components when seeking a reliable solution for valvetrain maintenance or performance tuning.

Manufactured by Manley from high-strength steel, these Super 7 Valve Locks - .050in feature a durable black oxide finish to resist corrosion and wear. The "Super 7" designation refers to the 7-degree taper, which is a standard in performance racing for its ability to distribute pressure evenly across the retainer. A critical specification of this set is the .050-inch reduced height, which allows for increased spring pressure or clearance adjustments without changing the valve itself. This precision machining ensures that each lock in the 16-piece set maintains consistent tolerances across the cylinder head.

Engineered for professional-grade applications, the Super 7 Valve Locks - .050in are compatible with a wide range of aftermarket retainers designed for 7-degree locks. These components are particularly beneficial for racers and mechanics who need to fine-tune installed spring heights for optimal engine performance. Before installation, users should verify valve stem diameter to ensure a perfect fit with these 0.341-inch specific locks. Reviewing the specifications of your existing valvetrain setup will confirm that these components provide the necessary clearance for your specific camshaft profile.
