TRAXXAS TRX4 Front Gear Box Aluminum 15 pcs set by GPM TRX4012B  [TRX4012B]

Aluminum front gear box for TRX4

This GPM aftermarket front gear box is produced for the TRAXXAS TRX4 Trail Crawler and supplied as a 15 pcs set without the cover, designed as an RC-scale replacement and upgrade for the TRX4 front assembly. The set focuses on mechanical stability rather than cosmetic change, and it integrates with the TRX4 front drivetrain to secure the front differential and related linkages.

Construction uses 6061-T6 aluminum for a balance of light weight and tensile strength, intended to reduce flex where the front differential, suspension links, and front axle mount interface. The package omits the cover, so installers should reuse the original cover or fit a compatible aftermarket cover when required by their setup.

Primary functions: stabilize the front differential parts, secure suspension links, and provide a mount for the front axle link set and front C hub. The part set is intended for hobby-scale RC crawling and trail use on TRX4 models.

Use this GPM front gear box where additional front-end rigidity is needed on TRX4 trail crawlers, and confirm fastener reuse or replacement to match your existing cover and mounting hardware.
