Traxxas TRX4M Bronco and TRX-4M Defender Direct-Fit Brass Axle End Covers - JR-TRX4M03-BK by Jazrider  [JR-TRX4M03-BK]

Direct-fit brass axle end caps

This scale RC axle cover set is made for the Traxxas 1/18 TRX4M Bronco and TRX-4M Defender chassis variants, finished in a black coating applied over brass. The parts install as external axle end covers to alter the appearance and add axle-end mass on a scale crawler.

Machined from brass with a black finish, these covers attach to the axle housings of the specified Traxxas TRX4M models using the existing mounting points. They provide a simple visual upgrade or replacement for the visible axle end caps without requiring changes to internal axle components.

From an installation standpoint the brass construction increases axle-end weight compared with lighter materials, which can change slow-speed traction feel and the vehicle attitude on technical sections. Fitment uses factory cover mounting locations on compatible TRX4M Bronco and TRX-4M Defender units; verify alignment before permanent installation.
