Rear Gear Cover Aluminium for TRAXXAS X-Maxx TXM038M by GPM  [TXM038M]

Rear gearbox armour plate

This aluminium rear gear cover is an aftermarket accessory crafted by GPM for the TRAXXAS 1/8 X-Maxx chassis. Sold as a single unit, it fits the rear gearbox region to deliver a rigid protective plate over the spur gear and adjacent housing. It is intended for electric 1/8 off-road hobby use and is described here to assist with fitment and routine checks.

Fitting is direct for users with basic X-Maxx maintenance experience: remove the factory plastic cover if present, place the aluminium plate over the rear gearbox opening, and secure using the original screws. The plate enhances structural protection and supports stable spur gear alignment during demanding runs, while making inspections and mesh checks easier.

When integrating into a tuned X-Maxx, confirm that there is clearance for the motor pinion and spur gear, ensure it does not impinge on suspension travel or driveshaft operation, and check that any reused fasteners sit flush with the aluminium surface. The cover is a passive part and does not change drivetrain tuning.

For drivers wanting a tougher rear gearbox barrier, this aluminium cover is a simple upgrade that protects the spur gear area and eases maintenance checks.
