- Oil pressure regulation bypass routes excess oil directly to the supply side of the pump & reduces the amount of oil returned to the tank, less foaming and cavitation
- Ideal for scratch built applications where the builder is starting out with aftermarket crankcases, or older engines where a complete overhaul is required
- Machined with an oil pressure relief bleed off passageway & relieves pressure build up on top of the valve to maintain consistent oil pressure
- S&S® pinion and oil pump drive shaft drive gears increase potential oil volume delivery by 25 percent over stock on 1972 and earlier engines
- The standard pump cover allows total flexibility for oil system configuration with a number of oil feed and return options
- Same width oil supply and return gears as the stock HD® aluminum pump
