Rear bumper mount engineered for TRX4

This aluminium rear bumper mount is supplied as a 7 pcs upgrade kit for TRAXXAS TRX4 TRAIL CRAWLER vehicles under model TRX4331R. The component is engineered to provide a stable rear fixing point on the scale chassis to reduce local flex where the bumper is anchored.

Installation requires simple removal of the stock bumper mounting hardware and use of the included fasteners. The mount secures the bumper, retains alignment under load, and offers a concise tuning point to adjust rear attachment stiffness without altering suspension geometry.

How does this mount affect bumper alignment?

The mount provides a more rigid anchor at the bumper interface which reduces deflection under load and helps maintain consistent alignment during crawling.

Are the supplied fasteners standard sizes?

Yes, the kit includes M4x2.5×15 screw shafts and stainless 3×6 round head screws to match common TRX4 mounting points.

Does the bracket require chassis modification?

No permanent chassis modification is expected for standard TRX4 bumpers; the part uses existing attachment points but confirm fit before final tightening.

What maintenance is recommended?

Keep mating surfaces and fasteners clean after runs, inspect for wear or loosening, and re-torque fasteners as part of routine maintenance. Write Product Review Please sign in your account before you can write any review. Sign In Close
