S&S Camshaft - Easy Start - 557 Gear Drive - Twin Cam '07-'17 / Dyna '06

The S&S Camshaft adds power and throttle response with a performance cam profile built for your engine.

This is the 557 Series grind. See the cam specs for lift, duration and valve events, and confirm your engine's compression and valvetrain are matched to the cam before installing.

Fits Harley-Davidson Touring (2007-2017), Softail (2007-2017) and Dyna (2006) models. Check the fitment chart below to confirm your exact year and model.

• 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
