Description
Valve lock failure is a catastrophic engine event—it leads to dropped valves, bent pushrods, and bent valves that destroy your entire cylinder head. Manley’s 7 Degree Super Valve Locks eliminate this risk with precision engineering and proven durability in high-RPM and forced-induction applications. Whether you’re building a naturally aspirated stroker or a turbocharged race engine, these locks provide the security and reliability your valvetrain demands.
The 7-degree geometry provides superior grip on modern valve stems while distributing load evenly to prevent stem galling. The bead-loc design locks the keepers in place with absolute certainty, giving you confidence that your valvetrain will hold together under extreme conditions.
