TRAXXAS TRX4 Rear Gear Box Mount Upgrade 12pcs TRX4013C by GPM  [TRX4013C]

Precision rear gearbox mounts for TRX4

The TRX4013C kit is a 12pcs aluminium mounting solution engineered for the TRAXXAS TRX4 Trail Crawler chassis, intended as a durable aftermarket replacement for rear gearbox mounting points. Machined from 6061 T6 aluminum, these components provide a rigid interface between the rear gearbox and rear knuckle arms to help preserve drivetrain alignment under crawling loads.

The parts employ a C-clamp style contact to engage the rear knuckle arms, simplifying setup during installation and reducing dependence on plastic locating tabs. The kit is dimensioned for hobby-grade RC vehicles and is designed to mate with TRX4 rear hardware 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. Use standard hand tools and a 2.5mm hex driver to torque the fasteners evenly and verify drivetrain alignment after fitting.

Service notes: confirm suspension and knuckle clearance during test fitting and recheck fastener torque after a brief run to ensure the C-clamp interface has seated correctly. These mounts are intended to deliver a more stable mounting location for tuning and maintenance on the TRX4 Trail Crawler platform.
