GPM Racing Aluminium Front/Rear Differential Carrier-5pcs Set for Traxxas 1/10 TRX4 (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.

Specifications

• Item Aluminium front/rear differential carrier, 5pcs set
• Material Aluminium
• Model Number TRX4011
• Compatibility TRAXXAS TRX4 TRAIL CRAWLER
• Weight 92g per piece (with rolling beads)

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

Is machining or shim work required for installation?

These carriers are produced to match TRAXXAS TRX4 diff housing dimensions and are intended for direct fitment without additional machining in standard vehicle builds.

What hardware and fasteners are included?

The package specifies stainless steel round head screws 2.5*6 (4pcs) for mounting; validate the supplied hardware before starting the install and keep factory fasteners if needed.

How does aluminium construction affect thermal performance?

CNC aluminium offers superior passive thermal conduction compared with polymer carriers, reducing localized heating and helping maintain gear tolerances during prolonged operation.

Are there fitment issues with the supplied hex adapter?

The supplied 9mm widened hex adapter is 4mm wider than the original hex specification; inspect wheel and hub clearance prior to final assembly to ensure compatibility. Write Product Review Please sign in your account before you can write any review. Sign In Close
