TRAXXAS TRX4 Trail Crawler Aluminum Lower Spur Gear Case Shield TRX4038GCB by GPM  [TRX4038GCB]

Aluminum lower spur gear case shield plate

This aftermarket lower spur gear case cover serves as a scale replacement for the TRAXXAS TRX4 Trail Crawler platform. It is designed to shield the motor compartment and main spur gear from impacts and contamination while retaining straightforward service access.

Produced from aluminum 6061 T6, the cover gives improved tensile strength over stock plastic housings and creates a stiff barrier around the gearbox opening. The item is supplied as a 7 pcs kit and includes stainless steel round head screws for mounting, listed below. Several finish options are offered to complement or personalise a TRX4.

Fitment and setup notes:

• Installs in place of the factory lower spur gear case cover to provide a more robust enclosure without altering gearbox geometry.
• The alloy panel helps keep grit and debris away from the spur gear and motor, which can reduce wear at the spur and pinion interface during slow technical crawling.
• As the part is rigid, confirm clearance around the motor, pinion and any aftermarket ESC or wiring before final tightening to avoid binding.

This GPM aluminum lower spur gear case cover is a clean, effective metal upgrade for TRX4 owners seeking reinforced protection without losing service access.
