S&S specifically developed the new bolt-in 557 Easy Start cams for the HD® Tri Glide®. The short duration produces lots of torque, and the automatic mechanical compression release makes the engine a snap to start! Stock cam base circle allows use of stock pushrods, but we recommend the S&S Quickee pushrods for easy installation. Available in chain drive and gear drive versions. Boost your performance even more with an S&S 31/2" round touring muffler and S&S Power Tune Dual header system.

• Reliable - tested for 100,000 accumulative starts and over 150,000 road miles without breakage or compression release failure
• Start any engine with a stock starter
• Can be used with stock valve springs
• Automatic - no buttons to push
• Save your starter and battery
