Manley valve springs are wound from super clean alloy. Each design minimizes stress to ensure long service life with high lift camshafts. Retainers are manufactured in our own double spindle CNC machines to exacting tolerances and precise installed height specifications. Locators are manufactured in our own CNC lathes. Heat treated and black oxided after machining. Valve locks are manufactured in our own Swiss turning centers with rigid control over the all-important angle to ensure precise mating with the retainer. |
