This replacement rear bumper suits the Traxxas TRX-4 Defender chassis and carries the model number JR-TRX433. The stainless steel diamond plate is used to provide a textured, slip-resistant rear step for scale trail use.
Sold as a single replacement piece, the bumper is intended to mount at the Defender's original rear bumper location. Confirm your model's mounting points and fastener lengths before installation to ensure proper fit and secure attachment.
The item is focused on adding scale realism and a non-slip rear platform; it does not affect drivetrain, suspension, or electronics. Note that rear weight distribution may change slightly after fitting, so check balance and clearance after installation.
