Product Information
Conversion kit uses Kibblewhite racing springs combined with a lightweight valve spring retainer that houses a standard 9.5 mm hardened steel shim
Rocker arm rides directly on the 9.5mm shim surface, allowing for a significantly greater rocker arm swipe surface area
Increased rocker arm surface contact area allows the ability to run higher lift cams than previously could not be used with valves having a 6mm valve stem
Rocker shim thickness can be varied by changing shim size to adjust the effect valve stem protrusion height
Increase in valve stem protrusion height with this kit is approximately 0.100"
Feature interference-wound, double-chrome silicone springs
Made in the U.S.A.
