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

Aluminium rear gear cover

This aluminium rear gear cover is an aftermarket RC-scale accessory produced by GPM for the TRAXXAS 1/8 X-Maxx platform. It is sold as 1pc and fits the rear gearbox area to provide a rigid protective panel over the spur gear and surrounding housing. The part is intended for hobby use on electric 1/8 off-road setups, and is described here only in the context of model maintenance, fitment, and tuning.

Installation is straightforward for users familiar with X-Maxx maintenance: remove the existing plastic cover if present, position the aluminium cover over the rear gearbox opening, and refit the original mounting hardware. The cover's role is primarily structural protection and consistent alignment of the rear spur gear during aggressive runs; it can also make post-run inspections easier by providing a stable access point to check gear mesh and bearings.

When integrating this cover into a tuned X-Maxx, confirm clearance for the motor pinion and spur gear, ensure no contact with suspension travel or driveshafts, and verify that any re-used screws seat flush against the aluminium surface. Do not modify motor or speed controller settings as part of fitment; the cover is a passive component intended to protect and stabilise the gearbox area rather than alter drivetrain performance.

For model builders who want a more rigid rear gearbox shield, this aluminium cover provides a simple upgrade path that helps protect the spur gear area and assists routine inspection without changing drivetrain settings.
