Manley titanium retainer (RET-TI 1.255, 7 deg for LT4) is CAD-designed to reduce mass while retaining strength for Chevrolet LT4 applications. Use Manley P/N 13098 or OE LT valve locks; the retainer increases installed height slightly and requires seven valve locks. Machined from 6AL-4V titanium and optimized for minimal mass, it supports higher RPM potential and improved valvetrain stability when used with recommended locks.
