Atomic Billet Oil Pump OEM Housing Rebuild Kit – Ford Barra DOHC

The factory Ford Barra oil pump internals are a weak link in high-performance engines — especially when subjected to big boost, high RPM, and aggressive drivetrain shock. The Atomic Billet Oil Pump Rebuild Kit is designed to transform your OEM alloy pump housing into a race-ready, high-flow, high-pressure unit using the same components trusted in Atomic’s own engine program.

This complete kit includes tight-tolerance billet steel gears, a gas-nitrided chromoly (CRMO) backing plate, a high-pressure relief spring, and all necessary seals and hardware. Built to withstand the torsional loads of crank-driven oil pumps — especially in manual transmission cars — this kit ensures rock-solid pressure and long-term reliability.
