S&S CYCLE - 106-5737 - Camshaft Kit - Easy Start - 551 Gear Drive - Twin Cam '07-'17
For riders who demand quality in every component, the S&S CYCLE 106-5737 is a camchest kit built to the standards that experienced powersports enthusiasts recognize the moment they put it in their hands. Allows 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. Optimized for 88”/96”/103” to 106” Touring bike with slip-on mufflers and 9.0:1 to 9.0:9 compression with stock starter, giving you a level of quality that holds up across the full service life of the component. Bolt-in for stock or mildly modified Touring models. Greatly improves low-end and midrange torque. Strongest from idle to 4000 rpm. Whatever the application demands, the 106-5737 gives you a component built to meet it. Sold as a complete kit.
