Traxxas TRX-4 Defender Compatible Rear Bumper - Aluminum - JR-TRX428-BK by Jazrider  [JR-TRX428-BK]

Aluminum rear bumper crafted for TRX-4 Defender compatibility

This aluminum rear bumper is produced by Jazrider as a replacement for the Traxxas TRX-4 Defender, focusing on fitment accuracy and rear protection for scale trail use. It offers a metal alternative to stock plastic bumpers while matching the Defender rear mounting layout.

Compatibility and intended use — The bumper is made for TRX-4 Defender models and acts as a component upgrade for pilots wanting a sturdier rear mount and improved scale styling. It is designed to integrate with the TRX-4 chassis without impacting drivetrain or suspension geometry.

Fit and installation guidance — Installation uses the existing factory rear mount points; remove the stock bumper and refit using the original screw locations where possible. Have small hex drivers ready and check thread engagement before final torque; do not force screws into misaligned holes.

Practical impact — As a structural hop-up, this aluminum bumper increases attachment durability and pairs well with other scale accessories. It is intended for trail protection and appearance rather than to change vehicle dynamics.

Select this aluminum rear bumper to improve rear-end robustness and achieve a metal scale look while maintaining TRX-4 Defender mounting compatibility.
