Triumph 650 Chrome Silicon valve spring set

Regular price $54.24 $0.00

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 OEM 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". Replaces Triumph part number 99-7037. These springs are much higher quality than the current UK production and would be great for use with E3134 or other stock Triumph cams.
