Triumph Unit 500 racing valve spring kit!

Friday, Apr 08, 2016

You don’t actually have to race to take advantage of this excellent lightweight spring kit from Kibblewhite. Engineered for the Unit construction 500cc head, this kit features titanium collars with dual springs, and uses the stock 7 degree Triumph keepers.

We have found some currently manufactured “UK MADE” spring sets to be inadequate in both seat pressure and open pressure, and we have even seen valve springs that are almost at coil bind with stock cams! Most shops that sell these inferior spring sets do not own a spring tester, nor will they pay for the repair if your engine destroys itself.

This kit has been proven in racing and on the street for years.


We do not sell any valve springs that do not have a manufacturer’s name on the package.

Our intimate knowledge of camshafts and valve train, as well as our practical
experienceof using these in our engines have proudly made us the
number one dealer for Kibblewhite Triumph parts in the USA.
