Manley Ti-17 spring retainer, 1.500 in diameter with +.100 height and 7° lock angle, is CNC machined and CAD designed to reduce valvetrain mass while maintaining strength. Weighing 15.0 grams and sized for an 11/32 in valve stem, it requires 7° valve locks and a 1.500 in spring diameter. Use this retainer where lower reciprocating mass and precise tolerances are important for valve control and RPM response.
