TRAXXAS TRX4 Front and Rear Diff Carrier Set 5pcs CNC TRX4011 by GPM  [TRX4011]

Heavy-duty aluminium diff carrier for TRX4

This five-piece aluminium differential carrier set is an aftermarket solution for TRAXXAS TRX4 Trail Crawler platforms, supplying a robust support for both front and rear differential assemblies. The parts are CNC machined with a 3D surface finish to minimise hot spots while preserving original drivetrain geometry.

Designed to protect and steady differential gears, these carriers promote more consistent gear engagement under load and help conduct heat away from the diff housing during long crawling sessions. They are intended to fit original diff gears and housings for a direct swap.

Assembly notes: included are stainless steel round head screws (2.5*6 - 4pcs) for mounting the carriers; where possible keep factory fasteners and recheck torque on all six mounts after the first run. The kit includes a 9mm widened hex adapter specified as 4mm wider than the stock hex, so confirm wheel hex compatibility before installation.

A direct-fit aluminium replacement for TRX4 differentials that increases chassis stiffness and improves passive thermal performance with minimal changes.
