Many an engine has been destroyed as a result of oil pump driveshaft failure. To cure this all-too-common problem, ARP has
designed an extra heavy-duty shaft that will provide you with the necessary reliability. The shaft is made from heat-treated, premium grade aerospace 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.
FORD DRIVES: Made from ARP2000 and heat-treated to 220,000 psi. These pump drives feature a CNC milled (not broached) hex, and has the retaining washer installed.
