TRAXXAS TRX4 Aluminium Front/Rear Differential Carrier 5pcs TRX4011 by GPM  [TRX4011]

Precision CNC diff carrier for TRX4

This five-piece aluminium differential carrier set is engineered for TRAXXAS TRX4 Trail Crawler platforms, providing a precision-machined mounting solution for both front and rear differential assemblies. Components are CNC machined with a three-dimensional finish to reduce thermal concentration while maintaining original drivetrain alignment.

From a performance perspective the carriers are designed to secure and stabilise differential gears to maintain consistent gear mesh under load and to assist passive thermal conduction from the diff housing during extended crawling operations. Fitment is intended for direct mating with original diff gears and housings to simplify installation.

Assembly notes: the set includes stainless steel round head screws (2.5*6 - 4pcs) for carrier attachment; reuse original fasteners where required and verify torque across all six mounting points after initial runs. The kit incorporates a 9mm widened hex adapter specified as 4mm wider than the stock hex, so confirm wheel hex compatibility prior to final assembly.

A precision aluminium upgrade that increases structural rigidity and enhances passive heat transfer for TRX4 differentials while requiring minimal modification.
