S&S CYCLE Easy Start Cam Kit - Twin Cam 330-0303

Cold starts on high-compression big-twin engines demand more from your starter and battery than they should have to give. The S&S Cycle Easy Start Cam Kit solves this by temporarily reducing crank compression during initial ignition, allowing your stock starter to turn the engine over effortlessly—then automatically releasing full compression once the engine fires and RPM climbs. You'll extend starter and battery life significantly while eliminating the frustration of hard starts on displacement and compression builds that typically require upgrades to electrical systems.

This kit has been validated through 10,000 consecutive starts without battery depletion, making it a reliable solution for both street riders and race engines that demand consistent, hassle-free starting performance.
