Atomic Billet Oil Pump Gear Set – Ford Barra 4.0L DOHC | CNC Billet Steel
Description:
The factory powdered metal oil pump gears in Ford Barra engines are a known failure point — especially under high RPM, big boost, or aggressive manual transmission use. The Atomic Billet Oil Pump Gear Set replaces those weak links with a precision-machined, heat-treated billet steel gearset, purpose-built for reliability in high-performance environments.
Whether you're rebuilding your OEM housing or preparing for serious power, these gears are the same tight-tolerance sets used in Atomic’s Race Series and Full Steel oil pumps
✅ Key Features:
