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. The aluminum retainers only weigh 8 grams each! Depending on your installation height seat pressure will vary. We have used this kit on street bikes and race engines and it has proven to be a winner.
