TRAXXAS TRX4 Front Gear Box 15-piece 6061-T6 TRX4012B by GPM  [TRX4012B]

6061-T6 aluminium front gear box for TRX4

This aftermarket front gear box is intended for use with the TRAXXAS TRX4 Trail Crawler and is supplied as a 15 pcs set without the cover. It functions as a practical replacement and upgrade to improve front-end rigidity on TRX4 models while keeping a scale-accurate appearance.

Constructed from 6061-T6 aluminium to deliver reduced flex at critical junctions, the part supports the front differential, suspension links and axle mounting area with a stiffer interface. Because the cover is excluded, you should either reuse the original cover or fit a compatible aftermarket cover to complete the installation.

Main benefits are improved stability of front differential parts, firmer suspension link attachment, and a solid mounting point for the front axle link set and C hub. The set is aimed at hobby-scale crawling and trail driving where chassis stiffness matters.

Use this front gear box where you need extra chassis stiffness on TRX4 crawlers, and check which screws you will reuse or replace to align with your chosen cover and mounting hardware.
