S&S CYCLE Easy Start Cam Kit - Twin Cam 106-5807

Cold-starting a high-compression engine puts unnecessary strain on your starter and battery—especially in harsh conditions or after extended storage. The S&S Cycle Easy Start Cam Kit solves this problem by temporarily reducing cranking compression until ignition occurs, then automatically returning to full compression once the engine fires up. You'll extend starter life, preserve battery capacity, and eliminate the frustration of grinding starts on heavy-duty Twin Cam engines.

This kit uses a centrifugally-retracted compression release lobe that engages only during cold starts. Once RPM builds, the mechanism retracts and your engine runs with zero performance loss—full compression, full power, no compromises. Tested for 10,000 consecutive starts without battery depletion, this is a proven solution for serious riders and engine builders who demand reliability.
