HPI Bullet 3.0 MT and ST Alloy Center Differential Housing by GPM BMT038  [BMT038]

Alloy center housing for HPI Bullet 3.0 MT/ST

This alloy center differential housing is an RC-scale replacement part designed for HPI Bullet 3.0 Monster Truck (MT) and Stadium Truck (ST) platforms. Offered as a 2pcs set, the housings replace the original center differential shell and serve as a structural support for the center gears and bearings within the center assembly.

Constructed from alloy for improved wear resistance compared with standard plastic shells, the housings provide a stiffer mounting point for the center differential, which can improve gear mesh consistency under load. The component is intended for use in 1/10 scale nitro MT and ST setups where the center differential housing is compatible.

Installation requires basic disassembly of the center gearbox, removal of the existing housing, transfer of bearings and internal gears, and secure reassembly using the original hardware. Check gear alignment and bearing seating during reassembly and perform a short test run to confirm smooth operation before full use.

Use this alloy housing to restore or upgrade the center assembly's rigidity and to maintain consistent gear engagement during tuning and regular maintenance.
