Upgrade Your OEM Housing to Race Spec

Why You Should Upgrade Your Oil Pump

The factory Ford Barra oil pump internals are a notorious weak link in high-performance engines. The OEM gears are made from sintered iron (compressed metal powder) which is brittle and prone to shattering under high RPM, boost, or drivetrain shock. The factory backing plate also flexes, causing pressure loss at high RPM.

💡 DID YOU KNOW?

Sintered gears shatter like glass. When you hit a hard rev limiter or launch aggressively, the harmonic shock travels straight to the crank-driven oil pump. Factory gears can disintegrate instantly, destroying your engine in seconds. Our Billet gears are engineered to absorb this shock and keep pumping.

The Atomic Solution

The Atomic Billet Oil Pump Rebuild Kit transforms your standard OEM alloy housing into a high-flow, race-ready unit. We replace the weak points with our Gas Nitrided 4340 Billet Steel Gears and a rigid Chromoly Backing Plate. This kit delivers the durability of a full billet pump at a fraction of the cost.

Complete Rebuild Solution: Gears, Plate, Spring & Hardware.
Gas Nitrided Gears and Backing Plate
Gas Nitrided for superior wear resistance.

2. Engineered for Longevity

We don't just machine them; we treat them. Our gears undergo a specialized Gas Nitriding process to create a hard, wear-resistant surface while maintaining a tough core.

  • Gas Nitrided Gears: Reduces friction and wear against the alloy housing, significantly extending pump life compared to standard billet gears.
  • Rigid Backing Plate: Our Gas-Nitrided Chromoly (CRMO) backing plate prevents "plate flex," ensuring oil pressure stays stable even at 8000+ RPM.
  • High Pressure Spring: Includes a specific high-pressure relief spring to bump oil pressure up for bearing protection under load.

⚠️ Critical Install Notes

  • Check Housing Wear: This kit is designed for serviceable OEM housings. If your housing is heavily scored or worn, it must be replaced to ensure proper oil pressure.
  • Cleanliness is Key: Ensure all parts and the housing are surgically clean before assembly. Any debris can score the new gears or housing.
  • Prime Before Start: Pack the pump with petroleum jelly (Vaseline) or assembly lube to ensure immediate priming on first startup. Dry starts kill pumps!
