Manley titanium retainers are manufactured in the very best dual spindle CNC machines to exacting tolerances rendering a superior jewel-like finish. We only use 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 revving Chevy, Ford or Chrysler engine. Their lighter mass allows the motor to turn higher engine speeds and still avoid dangerous valve float; without sacrificing reliability.
