This machined aluminum rear bumper mount in gun metal is an aftermarket accessory intended for the Traxxas TRX-4 chassis. It replaces the stock bumper mounting surface and is designed to work with the TRX-4 standard bumper hardware and mounting points.
The purpose of the component is to add a more rigid mounting location that helps keep the bumper aligned during scale trail use and obstacle work. Fitment presumes the original TRX-4 mounting pattern; installers should reuse stock fasteners or equivalent hobby-grade hardware to maintain thread engagement and chassis alignment.
Installation notes: verify hole alignment before torquing, tighten hardware gradually to avoid warping, and confirm clearance to scale accessories and body posts. Inspect and re-torque fasteners periodically to maintain serviceability.
