Looking to upgrade your Harley's oiling system? This S&S Cycle billet aluminum oil pump is a top-notch piece. The kit comes with everything you need: the pump, cover, mounting bolts, supply and return gears, drive shaft, check balls, springs, pressure relief valve, and all the little fittings, plugs, and gaskets. It's machined from billet aluminum here in the USA, so quality is on point. The design is smoother than stock, and the pressure relief towers are about 0.3 inches shorter for better fitment. It accepts the stock steel oil lines and uses the late-style mounting pattern. A direct bolt-on upgrade that can improve oil flow and reliability. Perfect for a rebuild or a performance build. Makes your engine happy. Replacement gaskets are sold separately if you ever need them.
