S&S CYCLE - 31-6307 - HVHP Oil Pump with Gears - Universal
The S&S CYCLE 31-6307 is a hvhp oil pump with gears - universal engineered for street applications where fit, function, and build quality are the baseline expectation. HVHP oil pumps have a new gear tooth profile with fewer but larger teeth that provides an increased oil volume for both supply and return-side of the pump. Supply-side gears are 9% wider than stock, giving you a level of quality that holds up across the full service life of the component. Return gears are 28% wider than stock to ensure that the additional volume of oil supplied to the engine is scavenged and returned to the oil tank, reducing the amount of oil in the crankcase breather. Kit includes supply gears, return gears, drive shaft, drive shaft keys, drive shaft snap rings, check ball, check ball spring, pressure valve spring, cover screws with O-rings, miscellaneous hose fittings, plugs, screws, gaskets, mounting hardware, oil pump drive shaft gear, oil pump pinion shaft gear, S&S breather gear and shim kit and instructions. Universal cover has a number of oil feed and return options allowing maximum flexibility for custom installations. For riders who know the difference quality components make, the 31-6307 is the right call. Sold as a complete kit.
