*** IN STOCK SHIPS TODAY *** RCD/P&P adjustable low pressure oil pump spring. Will work with RCD wet or dry sump oil pumps. Comes with two springs one goes inside the other one and allows the racer to drop the oil pump pressure down in applications where high oil pressure is not needed.
Outer spring measures 2.450" x .490", inner spring measures 2.550" x .335". Low pressure spring should give a racer 100 to 150 PSI of oil pressure on a race engine but oil weight and clearances will have an effect on final oil pressure.
