The JR-TRX4M02-BK package contains brass front caster blocks (C-hubs) intended for 1/18 scale Traxxas TRX-4M rigs. These direct-replacement parts fit the TRX4M Bronco and TRX-4M Defender and are supplied with a black finish.
These C-hubs define caster geometry at the front axle and interface with steering knuckles and hub carriers on the TRX-4M. The brass construction increases component mass and alters wear and steering feedback compared to plastic originals, which can affect front stability in technical trail use.
Fitment reminder: confirm dimensional fit with the stock C-hubs, check for clearance to the servo and steering links, and ensure all fasteners align with the TRX-4M mounting pattern before final tightening. The component is offered as an RC spare for hobby use only.
Compatibility: Traxxas 1/18 TRX4M Bronco, TRX-4M Defender.
