CAM KITS EASY START - S&S

Start any engine regardless of displacement or compression ratio with a stock starter


Save your starter and battery; tested for 10,000 starts without running battery down


Allow for easy start by initially reducing crank compression, but once the engine starts and rpm increases, the compression release lobe is centrifugally retracted and the engine runs normally, with full compression, and without any loss in performance


Available in chain drive and gear drive versions


All chain-drive cams include installation kit


All gear-drive cams include 4-gear set and installation kit


Gear-drive cams also available with inner gears only; intended for cam replacement for motors that have already been converted to an S&S gear-drive system


Made in the U.S.A.
