TRAXXAS TRX4 Trail Crawler Aluminum Front/Rear Differential Carrier 5pcs set by GPM TRX4011  [TRX4011]

Aluminum diff carrier for TRX4

This 5pcs aluminum differential carrier set is an RC-scale upgrade intended for use on TRAXXAS TRX4 Trail Crawler platforms, providing a durable mounting point for front and rear diff assemblies. The parts are CNC machined with a three-dimensional streamlined finish to reduce hot spots and to present a metallic appearance without altering original drivetrain geometry.

Functionally the carriers are designed to protect and stabilise the differential gears so they run more consistently under load and to assist passive heat dispersion from the diff housing during extended crawling sessions. Fitment is intended to mate with original diff gears and housings for a straightforward swap.

Assembly notes: the set includes stainless steel round head screws (2.5*6 - 4pcs) for securing the carriers; retain original fasteners where applicable and check torque on all six mounting points after the first run. The set uses a 9mm widened hex adapter which is stated as 4mm wider than the original hex, so verify wheel hex compatibility before installation.

For trail crawling drivers who want a direct-fit aluminum replacement to add rigidity and improved thermal behaviour to their TRX4 diffs, this carrier set offers a CNC-machined option that installs with minimal modification.
