S&S HVHP Oil Pump & Gear Kit

Originally designed for S&S 4-1/8″ bore V-Series engines with piston oiler jets, these high volume high pressure oil pumps also work well in stock Harley-Davidson Evolution engines and S&S V-Series engines.

Choose from two connection type options:

Universal cover has a number of oil feed and return options, allowing maximum flexibility for customized applications

Standard style cover has feed and return holes in the stock locations

No thicker than a stock pump

Gears with fewer, but larger teeth provide increased oil volume for both supply and return sides of the pump

Supply gears are 9% wider than stock and standard S&S oil pumps

28% wider than stock return gears ensure proper crankcase scavenging, reduce drag on the flywheels, and eliminate oil carryover
