The JR-TRX4M02-BK set contains brass front caster blocks (C-hubs) intended for 1/18 scale Traxxas TRX-4M vehicles. These parts are offered as direct replacements for the TRX4M Bronco and TRX-4M Defender and include a black finish.
As functional parts the C-hubs establish front caster geometry and interface with the steering knuckles and hub carriers on the TRX-4M front axle. Brass increases component mass and modifies wear and steering feedback compared to plastic stock parts, influencing front stability on technical terrain.
Before final assembly, verify fitment against the original C-hubs, ensure servo and steering link clearance, and confirm that fastener alignment matches the TRX-4M mounting pattern. The component is for hobby RC use only.
Compatibility: Traxxas 1/18 TRX4M Bronco, TRX-4M Defender.
