10 Degree Bead Loc Valve Locks +.050in

The 10 Degree Bead Loc Valve Locks +.050in from MANLEY are precision-engineered valve locks designed for high-performance engine builds and modifications. These locks are essential for securing valve springs under extreme RPM conditions, making them ideal for turbocharged, supercharged, and naturally aspirated performance engines.

The unique bead-loc technology features a dual-angle seat that locks the valve spring keeper securely, preventing spring surge and keeper lift at high RPM. The +.050-inch offset ensures correct valve-to-seat clearance on modified cylinder heads, while the 10-degree design optimizes spring seat geometry, reducing stress concentration and extending spring life.

These valve locks are particularly beneficial for engine builders working on displacement-increased, cam-upgraded, or supercharger-equipped platforms where standard components may fail under increased valve spring pressure. They are manufactured to high tolerances for consistent performance across numerous heat and rev cycles.
