Precision alloy centre housing for Bullet 3.0 centre assemblies

This alloy centre differential housing is a purpose-built replacement for the HPI Bullet 3.0 Monster Truck and Stadium Truck centre gearbox. Supplied as a matched 2pcs set, the housings replace the original centre shell and act as a rigid support for the centre gears and bearing surfaces inside the assembly.

The component uses a precision alloy construction to deliver improved wear resistance versus standard plastic shells while providing a firmer mounting point for the centre differential. The added stiffness helps keep gear mesh consistent under load, aiding predictable drivetrain behaviour in 1/10 scale nitro MT and ST setups where compatibility is confirmed.

Installation requires routine centre gearbox disassembly, removal of the factory housing, transfer of bearings and internal gears into the new housing, and careful reassembly using the original hardware. During reassembly verify gear alignment and bearing seating, then perform a controlled test run to confirm smooth operation.

Specifications

  • Item Center Differential Housing
  • Material Alloy
  • Model Number BMT038
  • Compatibility HPI Bullet 3.0 MT and ST (Nitro Engines)

Specified to restore or upgrade centre assembly rigidity and preserve consistent gear engagement during tuning and maintenance operations.

What should I inspect before fitting the new housing?

Inspect bearings for endplay or roughness and check internal gears for chipped or worn teeth. Replace any worn parts before transferring into the new housing.

Are any modifications required to bearings or shafts?

No machining of bearings or shafts is expected; transfer compatible bearings and ensure correct seating and preload when reassembling the centre gearbox.

How does the alloy housing influence gear mesh consistency?

The increased structural stiffness reduces flex at the centre mount points, helping to keep pinion and ring gear alignment stable under torque, which supports repeatable mesh settings.

Is this part suitable for high-stress nitro tuning?

The alloy housing is suitable for heavier duty use when fitted to compatible Bullet 3.0 centre assemblies, but always confirm overall drivetrain condition and replace any worn components to avoid secondary failures.
