S&S CYCLE Easy Start Cam Kit - Twin Cam 330-0459

If you're running a high-compression Twin Cam engine, cold starts become a wrestling match between your starter motor and combustion pressure. The S&S CYCLE Easy Start Cam Kit solves this by temporarily reducing crank compression during startup, allowing your stock starter to turn the engine over effortlessly—then automatically returning to full compression once RPMs climb. You'll extend starter and battery life while eliminating the frustration of labored cold cranks, especially in forced-induction or heavily modified applications.

This kit has been validated through 10,000 consecutive starts without battery depletion, making it a proven solution for engines where traditional starting becomes unreliable. Installation is straightforward with included hardware, though professional inspection of coil bind, valve-to-valve clearance, and valve-to-piston clearance is mandatory before assembly.
