Portal Drive Outer Housing for TRX-4

The JR-TRX406-HD outer portal drive housing is a brass replacement part made for Traxxas TRX-4 applications. It acts as the external housing for portal axle assemblies and is designed to replace the stock outer housings on compatible TRX-4 scale and trail crawler rigs.

As a heavy duty brass shell, the housing provides a firmer, longer-wearing exterior than many plastic alternatives and is selected for both strength and scale appearance. Its fit alters how the portal assembly mounts to the axle and is commonly installed on both front and rear corners for improved durability.

Fitment guidance: this unit replaces the factory outer portal housings and should be mated to the matching portal gear assembly on your TRX-4 chassis. Check clearance around brakes and suspension links, confirm proper thread engagement, and verify gear mesh after installation to prevent premature wear.

For scale builders seeking a metal outer shell, this brass housing is a fitting upgrade; always inspect fitment and alignment with TRX-4 portal gears during installation.

Is this housing suitable for all TRX-4 variants?

It is designed for Traxxas TRX-4 portal setups, but differences can exist between axle assemblies; verify the bolt pattern and bore dimensions of your specific variant before fitting.

Will I need different hardware for the brass housing?

In some cases longer or different grade fasteners are required to account for thicker material; check thread fit and replace any stripped or worn screws when fitting the new housing.

Can this part be used with aftermarket portal gears?

Many aftermarket portal gears are compatible, but confirm mating dimensions and clearances between the gear carrier and the new housing to ensure proper engagement.

What checks should I perform after installation?

After fitting, recheck gear mesh, spin the assembly by hand to detect binding, and perform a low-speed test to confirm there are no clearance issues with wheels, brakes, or links.
