Manley titanium retainers are manufactured in the very best dual spindle CNC machines to exacting tolerances, rendering a superior jewel-like finish using rugged and certified, heat treated aerospace grade titanium bar stock.
Retainer angles are held to within 6 (minutes) (this is a tenth of a degree) and installed heights are held to within .005"! Titanium retainers are a must for your high RPM Sport Compact engine. Their lighter mass allows the tuner to turn higher engine speeds and still avoid dangerous valve float; without sacrificing reliability.
