S&S CYCLE Easy Start Cam Kit - Twin Cam 106-5221

Harsh starter demands and drained batteries are common casualties of high-compression Harley engines—but they don't have to be. The S&S Cycle Easy Start Cam Kit solves this by reducing crank compression on initial startup, allowing your stock starter to fire the engine reliably without draining the battery or wearing out your starter prematurely. Once the engine catches and RPMs rise, the compression release lobe retracts automatically, restoring full compression and normal performance with zero compromise to power or efficiency.

Tested for 10,000 starts without battery depletion, this kit is engineered for riders who demand reliability from their high-performance builds. Whether you're running a modified 88, 95, 96, or 103 cubic-inch engine with compression ratios below 10:1, this is the practical solution to cold-start frustration.
