Replacement alloy housing for Bullet 3.0 MT/ST centre

This alloy centre differential housing is an RC replacement part intended for the HPI Bullet 3.0 Monster Truck and Stadium Truck centre assemblies. Supplied as a matched 2pcs set, the housings take the place of the original centre shell and provide a stable support for the centre gears and bearings.

Compared with standard plastic shells, the alloy construction improves wear resistance and gives a firmer mounting surface for the centre differential, which can reduce movement under load and help maintain consistent gear engagement. It is suited to 1/10 scale nitro MT and ST platforms where the housing is compatible.

Installation involves disassembling the centre gearbox, removing the existing housing, transferring bearings and internal gears, and carefully reassembling with the original fasteners. After fitting, confirm gear alignment and bearing seating, then perform a short test to ensure smooth drivetrain function.

Specifications

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

Choose this alloy housing to reinforce the centre assembly and keep gear mesh steady during maintenance and tuning sessions.

Is special tooling needed to fit this housing?

No specialised tools are required beyond basic RC workshop tools for gearbox disassembly and reassembly.

Can I use my existing internal gears?

Yes, transfer the original centre gears and bearings into the new alloy housing unless those parts are worn and need replacement.

Will this affect drivetrain noise or lash?

A stiffer housing can reduce flex-related lash variation, which often results in a more stable feel and can reduce noise caused by misaligned gears.

Is this suitable for high-power nitro setups?

The alloy housing increases rigidity compared with plastic, making it a good candidate for heavier duty or tuned nitro MT and ST drivetrains where compatibility is confirmed.
