Description
The Arp 1357901 Oil Pump Driveshaft Kit is a solution to the common problem of oil pump driveshaft failure in engines. It is made from premium grade 8740 chrome moly steel and heat-treated to 190,000 psi for extra durability. The shaft has a larger diameter than the OEM unit and is designed with a unique manufacturing process that allows for slight misalignment. This makes it suitable for handling increased torque requirements from larger capacity oil pumps or heavy viscosity lubricants.
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 premium grade 8740 chrome moly steel and heat-treated to 190,000 psi. The shaft diameter is a larger diameter than the OEM unit, and ARP uses a unique manufacturing process where the alignment sleeve is roll formed onto the shaft (not welded or pinned), enabling the sleeve to float and allowing for slight misalignment. These features combine to enable ARP shafts to handle the added torque requirements of increased capacity oil pumps or heavy viscosity lubricants.
