TRAXXAS TRX4 Rear Gear Box Mount Kit 12pcs 6061 T6 TRX4013C by GPM  [TRX4013C]

Rear gearbox mounting brackets for TRX4 Trail Crawler

This TRX4013C set provides a 12pcs aluminum mounting kit made for TRAXXAS TRX4 Trail Crawler chassis, supplied as a robust aftermarket replacement or upgrade for the rear gearbox mounting points. Machined from 6061 T6 aluminum, the components form a stiff interface between the rear gearbox and the rear knuckle arms to preserve alignment during technical trail and crawl use.

The mounts clamp to the rear knuckle arms using a C-clamp contact face, which makes positioning simpler during fitment and reduces reliance on fragile plastic tabs to hold the gearbox in place. The kit is intended for hobby-grade RC vehicles and is dimensioned 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 2.5mm hex driver to torque the fasteners evenly and verify drivetrain alignment after assembly.

Fitment notes: when installing the mounts, confirm clearance with suspension travel and rear knuckle movement, then recheck fastener torque after a short shakedown run so the C-clamp contact settles. The parts are intended to give a firmer mounting point for tuning and maintenance tasks on the TRX4 Trail Crawler platform.
