TRAXXAS TRX4 Rear Gearbox Brace Set 12pcs Aluminium TRX4013C by GPM  [TRX4013C]

Rear gearbox brace for TRX4 Trail Crawler

This TRX4013C kit contains a 12pcs aluminium mounting set designed for the TRAXXAS TRX4 Trail Crawler chassis as a sturdy replacement or upgrade for the rear gearbox attachment points. Made from 6061 T6 aluminum, the parts create a rigid link between the rear gearbox and knuckle arms to help keep driveline alignment under crawl and trail loads.

The mounting pieces employ a C-clamp style seating that grips the rear knuckle arms, simplifying alignment during installation and helping hold the gearbox without depending on thin plastic tabs. The kit is for hobby-grade RC models and is sized to align with TRX4 rear hardware as a direct-fit component.

Hardware supplied with the kit is stainless steel and includes flathead and cap screws to complete the installation: 2.5x10 - 6pcs stainless steel flathead screws and 2.5x16 - 4pcs stainless steel cap screws. Have basic hand tools and a 2.5mm hex driver ready to torque the fasteners evenly and check drivetrain alignment after fitting.

Installation tips: verify suspension and knuckle clearance before final torque, and recheck screw tightness after a short session to ensure the C-clamp contact has bedded in. The mounts are intended to provide a more dependable anchoring point for setup work on the TRX4 Trail Crawler platform.
