Triumph 750 beehive racing valve spring kit
This beehive spring kit for the Triumph 750 is not just for racing.
Beehive springs eliminate the need for dual springs, reduce the weight of both the spring itself and the valve collar, and eliminate the damaging harmonics and valve spring surge found in traditional valve springs. This kit will support up to .400" cam lift, and installs at 90# seat pressure at 1.380" (actual installed height may vary).This kit is suitable for all Triumph T140 and TR7 750 Twin heads, 1972-1980.
This kit includes 4 beehive springs, 4 HT steel retainers, and 4 HT lower collars.
This kit uses stock Triumph keepers(not included).
if needed new keepers may be added above.
