Super 7 Deg. Valve Locks 11/32in +.50

The Super 7 Deg. Valve Locks 11/32in +.50 by ISKY CAMS are precision-engineered components designed for high-performance engine builders and serious enthusiasts who demand reliability in extreme operating conditions. Valve locks are critical fastening elements that secure valve springs to the valve stem, preventing catastrophic valve float during high-RPM operation. This set of 16 locks is engineered specifically for 11/32-inch valve stems and delivers the exact geometry needed for engines running aggressive cam profiles, variable valve timing systems, or forced induction setups where standard locks may fail.

These valve locks feature a 7-degree lock angle geometry that optimizes the mechanical advantage between the lock, retainer, and valve stem, reducing wear and maintaining consistent spring preload across the entire valve lift cycle. Constructed from chromoly steel and finished in black oxide coating, the Super 7 Deg. Valve Locks resist corrosion and handle thermal cycling without degradation. The +.50-inch additional height specification allows these locks to work with modified valve spring assemblies or custom retainer stacks common in performance builds. The chromoly material provides superior strength-to-weight characteristics compared to standard steel, critical when valves are subjected to rapid acceleration and deceleration forces at elevated engine speeds.

Engine builders restoring classic muscle cars, constructing race-ready small-block or big-block mills, and tuning street performance engines rely on ISKY CAMS valve locks to prevent expensive valve train failure. Installation requires proper valve spring compressor equipment and should be performed by experienced technicians familiar with correct seating procedures. The set of 16 locks covers a full eight-cylinder engine with two locks per valve, ensuring complete valve train integrity. Compatibility with your specific build depends on valve stem diameter matching the 11/32-inch specification and sufficient clearance for the +.50-inch height dimension within your cylinder head and retainer assembly.
