Triumph 650 750 lightweight racing valve spring kit

This 650 & 750 spring kit will work with ANY high lift camshaft. This complete spring kit includes 4 7075-T6 hard anodized aluminum retainers, 8 heat treated steel keepers, 4 inner and 4 outer springs and 4 heat treated lower collars. This kit specifies 105# seat pressure at 1.425" installed height and is good up to .520" valve lift without coil bind.
