S&S Cycle TC3 Oil Pump Rotor Set Supply for 1999-Up Harley-Davidson Twin Cam
The supply rotor set is the heart of the TC3 oil pump’s ability to draw and deliver oil to your Twin Cam engine. Worn rotors reduce pumping efficiency and can cause dangerously low oil pressure, leading to accelerated internal wear. Replacing the supply rotor set restores the pump’s full output capacity, ensuring consistent oil delivery that protects your engine ride after ride.
