Valve Locks 10-Degree 11/32 w/Lash Cap Recess

Manley Valve Locks 10-Degree 11/32 w/Lash Cap Recess are precision-engineered components specifically designed for high-performance engine builds and competition applications where valve train stability is critical. These valve locks are essential for securing the valve spring retainer to the valve stem, preventing unwanted movement and potential valve float during aggressive cam profiles and high RPM operation.

Manufactured by Manley, a trusted name in performance valvetrain engineering, these locks feature a 10-degree geometry optimized for common valve stem angles, ensuring positive engagement with the retainer's locking groove. The 11/32-inch sizing accommodates standard small-block and mid-sized engine valve stems, while the integrated lash cap recess allows proper clearance for rocker arm geometry and provides a controlled surface for valve lash measurement and adjustment.

These valve locks are particularly beneficial for engine builders, drag racers, and enthusiasts running modified or naturally aspirated power plants. They are crucial for any engine featuring aftermarket or performance camshafts, roller rockers, or increased valve spring pressures, where OEM hardware may not provide the necessary reliability.
