TRAXXAS TRX4 Front Gear Box 15pc Aluminium Upgrade TRX4012B by GPM  [TRX4012B]

Front gear box in aluminium for TRX4

This aftermarket front gear box is made for the TRAXXAS TRX4 Trail Crawler and is provided as a 15 pcs set without the cover. It is intended as an accurate replacement and a chassis upgrade that concentrates on functional rigidity rather than visual alteration, integrating with the TRX4 front drivetrain to secure the differential and linkages.

Produced in 6061-T6 aluminium, the component aims to cut down flex at the joints where the front differential, suspension links and axle mount intersect, offering a practical balance of strength and weight. The cover is not included, so plan to reuse your original cover or fit a compatible aftermarket cover to complete the assembly.

Functionally the kit stabilises front differential parts, locks down suspension link attachments, and supplies a durable mount for the front axle link set and C hub. It is designed for hobby crawling and trail work on TRX4 platforms.

Fit this aluminium front gear box to gain additional front-end stiffness on TRX4 crawlers and verify fastener lengths and reuse to match your existing cover and mounting hardware.
