TRAXXAS TRX4 Precision Aluminium Gearbox Housing Set TRX4012 by GPM  [TRX4012]

Precision aluminium front and rear gearbox housings for TRX4 installations

The TRX4012 aluminium gearbox set is a CNC-friendly replacement designed to reinforce front and rear gearbox mounting points on the TRAXXAS TRX4 platform. These machined housings are intended to stabilise suspension link geometry, provide solid C-hub attachment interfaces, and reduce chassis flex at critical diff mount areas without altering the stock gear ratios or driveline topology.

Constructed to replace the original plastic housings, the aluminium cases increase structural stiffness around differential zones and help maintain alignment under low-speed technical crawling loads. Installation workflow requires disassembly of the OEM front and rear gearbox shells, careful transfer of the internal gears and bearings, and reassembly using the factory driveline components. No motor, ESC, or servo modifications are required for fitment.

The package details supplied list included fasteners as follows: Stainless Steel Cap Head Screw 2.5x14 - 4 pcs, Stainless Steel Flat Head Screw 2.5x10 - 4 pcs, Stainless Steel Flat Head Screw 2.5x6 - 6 pcs. These components secure gearbox halves, link mounts, and C-hub attachments according to the supplier information.

Engineered for hobbyists seeking precision and reduced flex at diff mounting points, the TRX4012 gearbox housings deliver a robust aluminium alternative to stock shells and include the stainless fasteners listed for reassembly.
