Many an engine has been destroyed as a result of an oil pump driveshaft failure. To cure this all too common problem, ARP has designed an extra heavy duty shaft that will provide you with all of the necessary reliability. The shaft is made from heat treated premium grade 8740 chrome-moly steel. Moreover, the shaft diameter is a larger diameter than the OEM unit. These features combine to enable ARP shafts to handle the added torque requirements of increased capacity oil pumps or heavy viscosity lubricants.
