S&S Cycle 557 Easy Start Camshaft Kit - 330-0053

Upgrade your heavy touring motorcycle with the S&S Cycle 557 Easy Start Camshaft Kit. This kit is specifically designed for Tri-Glides and other heavyweight bikes, offering improved starting performance and robust power delivery.

Description

The S&S Cycle 557 Easy Start Camshaft Kit utilizes a clever design that initially reduces crank compression for effortless starting. Once the engine fires up and RPM increases, the compression release lobe retracts, allowing the engine to run at full compression without sacrificing performance. This innovative approach ensures smooth starts and uncompromised power. The 557 grind camshaft delivers enhanced torque and horsepower throughout the RPM range, making it ideal for loaded touring bikes needing extra boost. Easy bolt-in design minimizes installation time.
