Triumph Unit 500 Lightweight "Racing" valve spring kit
This is the best spring kit in the world for the Unit 500 head, early or late.
No matter what camshafts you are running, stock, hot rod, or wild racing cams, this spring kit will work for you.
These high quality springs are wound with super clean chrome silicon wire that is then heat treated and shot peened. The ultra light titanium retainers reduce reciprocating weight and the base washers are specifically engineered for this kit.
Included are 4 titanium retainers, 4 inner and 4 outer springs, and 4 base washers. Keepers are NOT included as the retainers are designed to use stock keepers.
THIS KIT SPECIFIES 72# SEAT PRESSURE AT 1.200" INSTALLED HEIGHT AND IS GOOD UP TO .455" VALVE LIFT WITHOUT COIL BIND.
Don't take chances with unknown spring manufacturers, your valve springs are a very important part of your engine.
DEPENDING ON YOUR INSTALLATION HEIGHT SEAT PRESSURE WILL VARY.
