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
Gears with fewer, but larger teeth provide increased oil volume for both supply and return sides of the pump
Increased scavenging capacity results in less oil in the crankcase and less oil carryover
Excess oil from pressure control valve is filtered & longer pump life
Please review manufacturer details to ensure proper fitment before ordering.
