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.

NOTE: Installer must check coil bind, valve-to-valve clearance and valve-to-piston clearance.

NOTE: Due to the inherent characteristics of gear drives, you may experience more valve train noise.

NOTE: Not for models with OEM compression releases.
