Rear Gear Cover Upgrade Aluminium TXM038M by GPM  [TXM038M]

Precision aluminium rear gearbox cover

This aluminium rear gear cover is a CNC-quality aftermarket component from GPM designed for the TRAXXAS 1/8 X-Maxx chassis. Supplied as a single unit, the plate mounts over the rear gearbox opening to deliver a rigid protective surface that guards the spur gear and housing while improving inspection access. The part is intended for electric 1/8 off-road models and is presented with a focus on engineering fitment and durability.

Installation uses the existing X-Maxx mounting points: remove the factory plastic panel if present, align the aluminium cover with the gearbox aperture, and secure using the original fasteners or equivalent hardware. The cover provides structural reinforcement to the rear gearbox area and helps maintain accurate spur gear alignment under high-load impacts.

When integrating this upgrade into a tuned drivetrain, verify clearances for motor pinion and spur gear, ensure no interference with suspension or driveshaft travel, and confirm fasteners seat correctly on the aluminium surface. As a passive structural upgrade, the cover does not change gear ratios or require ESC tuning.

For precision-focused hobbyists seeking a durable rear gearbox shield, this aluminium cover delivers improved protection and consistent fitment without affecting drivetrain settings.
