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
