GPM TRAXXAS TRX4 Aluminium Transmission Upper Spur Gear Case Cover TRX4038GCA - Chassis Option  [TRX4038GCA]

Aluminium Upper Transmission Spur Cover

This aluminium upper spur gear case cover is a scale replacement part built for the TRAXXAS TRX4 Trail Crawler chassis. It provides a rigid metal layer over the transmission area to reduce impact transfer to the motor and main spur gear and to help keep dust and grit out during bush runs.

Designed to maintain gearbox opening alignment, the cover uses the original mounting points and supplied hardware. The set includes three stainless steel round head screws; start screws by hand and use conservative torque to protect plastic threads and mating surfaces.

Choose this cover when you prefer a metal alternative to the factory plastic part for longer service life on rough tracks. Double-check clearance at nearby body posts and suspension mounts before final fitment to avoid rubbing on standard TRX4 components.

A sensible aftermarket option for TRX4 drivers seeking a metal transmission cover; confirm fitment and screw torque during installation to keep gearbox alignment intact.
