GPM Racing Aluminium Rear Bumper (On-Road Street Fighter) - 7pcs Set for Traxxas 1/10 TRX4 (TRX4330RB)

Precision rear bumper for TRX4 installs

Constructed from T6 aluminium, this aftermarket rear bumper is a precision-focused option for TRAXXAS TRX4 Trail Crawler platforms that balances structural stiffness with a compact scale profile suitable for mixed terrain use.

In service it reduces transmitted impact loads to rear bodywork during light collisions and functions as a reliable mounting point for tail accessories or body panels. Width and height can be adjusted to match various shells and clearances, allowing precise rear overhang protection without chassis modification.

Installation follows a straightforward procedure using the supplied posts and stainless steel flat head screws. The package contains the hardware to attach to typical TRX4 mounting points; align components with body posts and torque carefully to preserve thread integrity.

Included parts from the product notes: Bumper Post – 2pcs, Stainless Steel Flat Head Screw 3×10 – 4pcs; the seller lists the item as a 7pcs set in the product title.
