Traxxas TRX4M Compatible Scale Brass Axle Covers for Bronco and TRX-4M Defender - JR-TRX4M03-BK by Jazrider  [JR-TRX4M03-BK]

Black-over-brass axle end covers

This accessory set is a scale axle cover kit intended for Traxxas 1/18 TRX4M Bronco and TRX-4M Defender models, featuring a black finish applied to brass. The covers provide an authentic axle-end look and add visible mass to the axle ends on these TRX4M chassis.

Constructed from brass with a dark surface treatment, the covers are designed to mount externally to the axle housings on the listed Traxxas models. They replace the exposed axle end caps without altering internal axle components, serving purely as a cosmetic and weight-change accessory for scale crawling.

Because the parts are brass, they increase axle-end weight versus plastic alternatives, which can affect the low-speed traction balance and stance when negotiating technical terrain. The finish is focused on scale appearance; expect normal surface wear with heavy trail use and confirm fitment on your specific TRX4M unit before committing to permanent installation.
