Atomic Billet Oil Pump Backing Plate – Ford Barra DOHC | CRMO Steel | Nitrided | Anti-Flex Upgrade
Description: In high-performance Barra engines, even the smallest component can make a big difference in reliability. The Atomic Billet Oil Pump Backing Plate is one of those parts — a critical upgrade that ensures your oil pump remains rigid, sealed, and pressure-stable even under extreme conditions.
CNC-machined from high-strength chromoly (CRMO) steel and gas-nitrided for surface hardness and wear resistance, this backing plate replaces the thin OEM unit, eliminating flex that can lead to pressure loss, cavitation, and gear wear — especially at high RPM or in high-horsepower builds.
✅ Key Features:
✅ Suits Ford Barra DOHC 4.0L 6-cylinder engines ✅ CNC-machined from chromoly (CRMO) steel ✅ Gas-nitrided surface for wear resistance and dimensional stability ✅ Eliminates flex and improves oil pump gear support ✅ Prevents pressure drop-off and pump distortion under load ✅ Ideal for builds with billet gears, high-pressure springs, or sustained RPM ✅ Used in all Atomic Race Series and Full Steel oil pump builds
🛠️ Why Upgrade to a Billet Backing Plate?
✔️ Factory plates can flex under high load, reducing oiling efficiency ✔️ Provides a solid foundation for billet gears and high-pressure systems ✔️ Reduces housing wear, gear deflection, and pump failure risk ✔️ Essential for high-boost, high-RPM, or circuit race applications ✔️ Cost-effective insurance for your engine’s bottom-end reliability
📦 What’s Included:
1x Gas-nitrided CRMO billet steel backing plate
Designed to bolt into OEM and Atomic-modified oil pump housings
