Description
Manley’s titanium retainers deliver the valve control and reliability demanded by high-RPM competition engines. By reducing mass at the valve train, titanium retainers lower inertia, allowing springs to work more efficiently and enabling higher lift profiles without float. If you’re building a forced-induction or naturally-aspirated engine that sees sustained high RPM, upgrading to titanium retainers is a direct path to stable valve actuation and extended component life.
