Traxxas TRX-4 Aluminum Lower Gear Cover for Defender and Tactical Unit TRX4038BA by GPM  [TRX4038BA]

6061 aluminum lower gear guard for TRX-4 platforms

This aluminium scale lower gear cover is designed for use on Traxxas TRX-4 vehicles and protects the centre transmission while adding a stiff mounting surface under the chassis. Machined from 6061 aluminum with a hollowed CNC profile, the part trims weight while exposing metal to improve passive cooling.

The plate helps control chassis twist and supports suspension link mounts by reinforcing the transmission area, reducing deformation during low-speed trail crawling. It is intended for hobby RC vehicles only and not for any full-size application.

All supplied hardware matches the original lower cover attachment points so the unit installs as a direct replacement on compatible TRX-4 variants.
