Details

There are many scenarios where a stock-volume oil pump won't provide the protection your engine needs. Engines with loose clearances (quick rebuilds or high-mileage engines) will need more oil volume to maintain a desired pressure. Engines operating at sustained high RPM (racing) also typically need more oil volume to maintain pressure in all oil galleries. 

These high-volume oil pumps move 25% more oil by utilizing 1.500" long internal gears, which is .300" longer than stock pumps. Another benefit of high volume oil pumps is increased pressure at idle, providing some much needed peace of mind on the street. These pumps come preset to 55-65 PSI of oil pressure, with an additional spring to change that pressure setting if needed.
