ARP OIL PUMP DRIVE SHAFT - ARP-134-7901

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.

CHEVY DRIVES: Made from premium grade 8470 and heat-treated to 190,000 psi, 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, allowing for slight misalignment.

IMPORTANT NOTE: Make sure you ALWAYS check clearances: shaft to block and pump to distributor.
