ARP 135-7902 Heavy Duty Oil Pump Driveshaft Kit

The ARP 135-7902 heavy-duty oil pump driveshaft kit is engineered to prevent the catastrophic engine failure that often results from stock driveshaft breakage. This premium shaft is manufactured from heat-treated aerospace grade chrome moly steel and features a larger diameter than OEM units, delivering the strength and reliability needed to handle high-capacity oil pumps and heavy viscosity lubricants.

Key Features:

• Premium grade 8740 chrome moly steel construction for Chevy applications, heat-treated to 190,000 psi tensile strength
• Unique roll-formed alignment sleeve design (not welded or pinned) allows the sleeve to float and compensate for slight misalignment
• Ford versions utilize ARP2000 material heat-treated to 220,000 psi for maximum durability
• CNC-milled hex design on Ford drives (not broached) ensures precise engagement and includes installed retaining washer
• Oversized shaft diameter provides superior torque handling capability compared to stock components

Important Installation Note: Always verify proper clearances between the shaft and block, as well as between the pump and distributor before installation to ensure correct fitment and function.

This kit provides the essential upgrade needed for high-performance engines, racing applications, or any build requiring bulletproof oiling system reliability.
