S&S 557 Easy Start Gear Drive Camshaft Kit

When choosing a cam for a vehicle like a Tri-Glide, you will be looking for a super torque cam to accelerate the extra weight.

S&S specifically developed the new bolt-in 557 Easy Start cams for the 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 or S&S Quickee pushrods.
