Melling Oil Pump Relief Springs, High Pressure, 70 PSI, Steel, Pink, Small Block Chevy, Set of 5

A higher pressure bypass spring in an oil pump forces more oil through the engine, while a lower pressure spring allows for more oil to be recycled within the pump. These Melling high-pressure oil pump springs allow you to replace your stock standard pressure spring with a higher pressure spring to keep your oil pump functioning at its optimum best.
