The JR-TRX431-BK fender set is an RC-scale accessory intended for the Traxxas TRX-4 Ford Bronco (82046-4). These rubber mud flaps mount to fender edges to reduce spray, protect painted shell areas, and improve scale authenticity. They are offered as replacement or upgrade components for the TRX-4 Ford Bronco RC model only.
Installation is aimed at hobbyists: align each flap with the Bronco's fender attachment points on the TRX-4 chassis and fasten with original or equivalent hobby screws. Depending on your body shell and tyre/wheel setup, minor trimming or clearance checks may be necessary before final fastening.
Primarily cosmetic and protective, the flaps do not change suspension or drivetrain characteristics. They keep mud and debris off the shell, help prevent paint chips, and provide an easy method to enhance scale looks while preserving core RC performance.
