S&S CYCLE Easy Start Cam Kit - Twin Cam 330-0057

Cold starts on high-compression big-inch Twin Cams demand serious cranking power—and that's where your starter and battery take a beating. The S&S Easy Start Cam Kit solves this by temporarily reducing compression during initial startup, allowing your stock starter to turn the engine over effortlessly. Once firing occurs and RPMs climb, the compression release lobe retracts automatically, restoring full compression and normal performance with zero loss in power or reliability.

Tested to 10,000 starts without draining your battery, this kit is engineered for riders who refuse to compromise on durability or upgrade to heavier electrical systems. Installation is straightforward with included components, and the cam maintains OEM-level valve train geometry for hassle-free fitment.
