Product Details
Highlights
- Allow for easy start by initially reducing crank compression, but once the engine starts and rpm increases, the compression release lobe is centrifugally retracted and the engine runs normally, with full compression, and without any loss in performance.
- Designed for Tri-Glides and other heavy bikes.
- Bolt in design.
- Includes camshafts, gearcover gasket, bearings, retaining ring, o-ring, threat lock and instructions.
- Made in the USA.
- Installer must check coil bind, valve-to-valve clearance and valve-to-piston clearance.
- Not for models with OEM compression releases.
S&S specifically developed the new bolt-in 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. 557CE, Tri-Glide.
