The Manley titanium spring retainer (RET-TI, 10° 1.560 double) is a machined titanium component intended for valvetrain builds that benefit from reduced rotating mass and accurate seating geometry in double-retainer configurations. It supports high-RPM control and is presented as a precision part for race and high-performance engines where titanium’s weight advantage complements exact manufacturing tolerances.
