TRAXXAS TRX4 Aluminium Transmission Upper Spur Gear Case Cover TRX4038GCA by GPM  [TRX4038GCA]

Precision Fit Aluminium Upper Spur Gear Case Cover

This aluminium upper spur gear case cover is an aftermarket replacement for the TRAXXAS TRX4 Trail Crawler platform engineered to provide a rigid protective layer over the transmission area. It reduces direct impact transmission to the motor and main spur gear and helps limit ingress of dust and debris during trail operation.

Installation preserves gearbox opening alignment using the original mounting points and supplied hardware. The kit includes three stainless steel round head screws; begin screws by hand and apply controlled torque to avoid stripping plastic receiving threads or disturbing gear mesh.

Use this cover as a durable metal alternative to the stock plastic upper cover when improved longevity and impact resistance are required. Verify clearance around adjacent suspension linkages and body mounts prior to final tightening to ensure no interference with TRX4 components.

A practical, application-focused aftermarket cover that supports reliable gearbox protection and fitment; follow the recommended screw torque and clearance checks during installation.
