Common questions
Will this oil pump rotor set fit my Twin Cam engine?
No, this S&S Cycle oil pump rotor set is specifically engineered for 2017 and newer Harley-Davidson Milwaukee-Eight (M8) engines only. Twin Cam models require a different part number for proper fitment.
Is this rotor set a direct bolt-in replacement for the stock M8 rotor?
Yes, this S&S Cycle rotor set is designed as a direct replacement for the stock oil pump rotor in Milwaukee-Eight engines, requiring no modifications to the pump housing for installation.
Does a higher-flow oil pump rotor increase horsepower?
While a higher-flow oil pump rotor set itself doesn't directly increase horsepower, consistent and adequate oil delivery is vital for engine reliability and cooling, which in turn supports the engine's ability to produce and sustain its full performance potential without premature wear.
