X-Maxx Rear Gear Protection Plate Aluminium TXM038M by GPM  [TXM038M]

Rear gearbox protection plate

This aluminium rear gear cover is an aftermarket scale accessory manufactured by GPM for use with the TRAXXAS 1/8 X-Maxx. Supplied as one piece, it fits over the rear gearbox opening to provide a rigid panel protecting the spur gear and surrounding housing. The part is intended for electric 1/8 off-road hobby use and is presented here for fitment and maintenance guidance.

Installation is simple for anyone used to X-Maxx service routines: remove the original plastic cover if fitted, align the aluminium plate over the rear gearbox aperture, and reinstall the existing fixing hardware. The plate reinforces the gearbox area and helps keep the rear spur gear alignment consistent during heavy use, while making routine inspections quicker.

Before running, confirm adequate clearance for the motor pinion and spur gear, ensure it does not interfere with suspension movement or drive shafts, and check that any retained fasteners sit flush on the aluminium face. This cover is a passive protective component and does not require ESC or motor adjustments.

For enthusiasts wanting a more rigid rear gearbox shield, this aluminium cover is a straightforward upgrade that protects the spur gear area while keeping servicing easy.
