TRAXXAS TRX4 Trail Crawler Aluminum Rear Gear Box Mounts 12pcs by GPM TRX4013C  [TRX4013C]

Aluminum rear gearbox mounts for TRX4

This GPM TRX4013C set provides a 12pcs aluminum mounting kit designed specifically for TRAXXAS TRX4 Trail Crawler chassis, intended as an RC-scale replacement or upgrade for the rear gear box mounting points. Machined from 6061 T6 aluminum, the parts act as a rigid interface between the rear gearbox and the rear knuckle arms to maintain alignment under trail and crawl use.

The mounting pieces use a C-clamp style contact to clamp to the rear knuckle arms, which simplifies positioning during installation and helps keep the gearbox seated without relying solely on plastic tabs. The kit is intended for hobby-grade RC vehicles only and is sized to mate with TRX4 rear hardware points as a direct replacement 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. Keep standard hand tools and a hex driver set on hand to torque the fasteners evenly and verify drivetrain alignment after installation.

Use notes: when fitting the mounts, check clearance with the suspension and rear knuckle movement, and recheck fastener torque after a short run to ensure the C-clamp interface has settled. The parts are intended to provide a more stable mounting point for tuning and maintenance tasks on the TRX4 Trail Crawler platform.
