S&S Cycle Chain Drive Cam Chest Kit without Cams w/Chrome Pushrod Tubes
Upgrade your cam chest with this S&S Cycle chain drive kit designed to refresh the oiling and valvetrain components on select Harley-Davidson motorcycles. The precision-machined billet aluminum cam support plate and oil pump feature removable passage plugs, independent scavenge sections for the flywheel cavity and cam chest, plus debris screens and an internal magnet to help keep contaminants out of the system. Increased oil flow on both the supply (44%) and scavenge (58%) sides supports consistent lubrication under demanding conditions. Quickee pushrods with pushrod tubes simplify installation and adjustment while adding a clean finished look. S&S precision tappets are hand-assembled to tight tolerances for reduced valvetrain noise, low leak-down rates, fast pump-up and stable high-rpm performance.
