Rear aluminium gear box for TRX4 upgrades

This is an RC-scale aluminium rear gear box set made for the TRAXXAS TRX4 Trail Crawler, supplied as a 15 pcs kit and sold without the cover. Machined from 6061-T6 aluminium, the components are intended to cut flex and increase lifespan at rear differential and suspension mounts.

The kit stabilises rear differential parts, secures the rear axle mount used by suspension links, and strengthens the rear C-hub mounting points during slow technical driving. Fasteners provided ensure the aluminium pieces fit the TRX4 rear assembly and aid correct alignment under load.

Specifications

  • Item: Aluminum Rear Gear Box (Without Cover) - 15 pcs set
  • Material: Aluminum 6061-T6
  • Model Number: TRX4013B
  • Compatibility: TRAXXAS TRX4 Trail Crawler

For trail drivers chasing a firmer rear end, this aluminium rear gear box set swaps out fragile plastic mounts and includes the screw kit for a straightforward upgrade that keeps rear geometry intact.

Does the set add much weight to the rear?

Aluminium will add some mass compared to plastic, but 6061-T6 offers a good strength-to-weight ratio and the extra weight often improves traction on technical sections.

Is any modification needed to install?

No major modification should be required for standard TRX4 rear assemblies; the supplied fasteners are intended for direct replacement mounting.

Will this affect axle articulation?

The parts reduce unwanted flex at the mount points while preserving the designed articulation of the axle and links for crawling performance.

Are replacement screws readily available?

Screws are included with the kit; if replacements are needed, standard metric stainless fasteners matching the original sizes can be sourced from hobby suppliers.
