TRAXXAS TRX4 Aluminum Front and Rear Differential Carrier 5pcs TRX4011 by GPM  [TRX4011]

CNC aluminium diff carrier for TRX4

This five-piece aluminium differential carrier set is an upgrade built for TRAXXAS TRX4 Trail Crawler rigs, giving a robust mounting point for both front and rear differential assemblies. Each part is CNC machined with a 3D-finished surface to reduce thermal hotspots while maintaining the stock drivetrain geometry.

In service the carriers help protect and stabilise the diff gears so they run more predictably under load and assist passive heat transfer away from the diff housing during extended crawling. The pieces are intended to mate with original diff gears and housings for a simple replacement.

Assembly notes: the kit ships with stainless steel round head screws (2.5*6 - 4pcs) for carrier fastening; keep original fasteners where required and recheck torque on all six mounting points after the first run. The included 9mm widened hex adapter is specified as 4mm wider than the factory hex, so confirm wheel hex fit before fitting.

For trail drivers wanting a direct-fit aluminium alternative to stock parts, this carrier set increases rigidity and improves passive thermal behaviour with minimal modification.
