Generally ships to addresses in the contiguous United States the same business day if ordered by 12:15PM Central Time!

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..
