Kibblewhite Chrome Silicon valve spring set


This spring set from Kibblewhite is an OEM replacement for Triumph 650 heads from 1966-1972. These springs can also be used on all 650 heads provided the taller basewashers are used ( Triumph p/n 70-6439).
This set consists of 4pc outer springs and 4pc inner springs.
Seat pressure is 68# @ recommended installed height 1.245"-1.255". Maximum recommended valve lift is .348". These springs are much higher quality than the current UK production and would be great for use with 3134 or stock cams.
