Fits 1984-'91 HD® Big Twins. 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 percent wider than stock and standard S&S® oil pumps. 28 percent wider than stock return gears ensure proper crankcase scavenging, reduce drag on the flywheels, and eliminate oil carryover. Polished Billet Finish. Increased scavenging capacity results in Less oil in the crankcase, Less oil carryover, Excess oil from pressure control valve is filtered & longer pump life.
