Ford Performance 289-302 Heavy Duty Oil Pump Drive Shaft Chromoly Steel M-6605-B302

Stock oil pump drive shafts are a common failure point in high-performance 289-302 builds, particularly under sustained RPM and boost. This chromoly steel shaft eliminates that weak link with a centerless-ground design and reinforced mid-shaft diameter that handles the demands of forced induction and aggressive track use. Whether you're running EFI or carbureted, this is the upgrade that keeps oil flowing reliably when it matters most.

The increased shaft diameter directly addresses the stress concentration that causes stock shafts to fracture under load. By starting with 4130 chromoly and precision-grinding out stress risers, Ford Performance delivers the durability your engine needs without requiring any modifications to existing oil pump housings—it's a straightforward bolt-in replacement.
