Description
Valve locks are a critical interface between your valve stem and rocker arm—any play or failure here means catastrophic engine damage. Manley’s titanium locks deliver the strength of premium materials with a 10-degree geometry designed to maintain positive lock engagement under extreme RPM and valve spring pressure. If you’re running a high-performance build or pushing factory limits, these are the locks that keep your valvetrain stable when it matters most.
