This RC-scale rear bumper is made for the Traxxas TRX-4 Defender chassis and is supplied under model JR-TRX433. The plate uses stainless steel diamond tread to deliver a textured, slip-resistant surface suited to scale trail access and rear loading tasks.
The part is supplied as a single replacement bumper intended for the TRX-4 Defender rear mounting location. Check your vehicle's existing bumper holes and fasteners to confirm fitment and whether any additional screws or spacers are required for installation.
When fitted, the bumper increases scale realism and gives a non-slip rear platform. It does not modify drivetrain, suspension, or electronics, though it can alter rear overhang mass slightly; verify balance after mounting to suit your setup.
