S&S CYCLE - 106-4868 - Camshaft Kit - 551G Gear Drive - Twin Cam | Dyna
For riders who demand quality in every component, the S&S CYCLE 106-4868 is a camshaft kit built to the standards that experienced powersports enthusiasts recognize the moment they put it in their hands. Designed for engines with 96 to 106 CID and 9:1 to 9:9 compression, this is a bolt-in cam set for stock or mildly modified touring bikes. Reverses the rear cam's direction of rotation, providing additional operating clearance between cam lobes making higher cam lifts possible, giving you a level of quality that holds up across the full service life of the component. More power across the rpm range, with improved low and midrange torque, strongest from 1,000-4,000 rpm. Increases valve timing accuracy by eliminating timing chain lash and loosely fit stock chain. Material must be removed from inner surface of the stock gear cover to install. Whatever the application demands, the 106-4868 gives you a component built to meet it. Sold as a complete kit.
