Alloy centre shell for HPI Bullet 3.0 MT and ST

This alloy centre differential housing is a replacement RC part for the HPI Bullet 3.0 Monster Truck and Stadium Truck platforms. The set includes two housings that replace the original centre differential shell and act as a rigid mount for the centre gears and bearings inside the assembly.

Alloy construction offers improved wear resistance over standard plastic shells and provides a firmer foundation for the centre differential, which helps hold gear mesh under load for more predictable drivetrain behaviour. Intended for compatible 1/10 scale nitro MT and ST setups.

Fitting requires basic gearbox teardown, removal of the existing shell, transfer of bearings and internal gears, then secure reassembly using the original hardware. Be sure to check gear alignment and bearing seating before a 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)

Install this alloy housing to improve centre assembly rigidity and help maintain consistent gear engagement during tuning and routine servicing.

Does this require any modifications to fit?

No permanent modifications are required when fitted to compatible HPI Bullet 3.0 centre assemblies; the housings are intended as direct replacements.

Are these sold as left and right halves?

Yes, the set contains both halves needed to replace the full centre differential housing.

Will using alloy change maintenance intervals?

Alloy is more durable than plastic, but routine inspection of bearings and gears is still recommended to ensure long term reliability.

Can this improve performance on rough tracks?

The increased stiffness helps maintain gear mesh under impact, which can contribute to steadier drivetrain performance on rough surfaces.
