This aftermarket rear bumper is built for the Traxxas TRX-4 Defender chassis and is listed as model JR-TRX433. The stainless steel diamond-plate surface provides a textured, slip-resistant area at the rear of the model for realistic access points.
The component is supplied as a direct replacement bumper intended for the Defender rear location. Before installation, confirm your bumper mounting holes and the length of existing screws to ensure correct seating and secure attachment.
From a tuning perspective, the bumper adds scale detail and a non-slip rear platform without altering drivetrain or suspension components. Be aware it can slightly change rear overhang mass, so reassess balance and handling after fitting to suit your tuning goals.
