Check out our new oil control system! We have eliminated the large brass bypass valve and machined it internally into our 6061 billet aluminum oil manifold housing. The systems are all calibrated to 80psi and includes a high flow relief piston double ground precision spring and complemented with the black anodized #8 fittings. The housing comes in blue black or red anodized color for a long lasting professional finish!JayCee Oil Control System Black
