Robust outer portal housing for TRX-4

This RC-scale outer portal drive housing is designed specifically for the Traxxas TRX-4 chassis and produced as model JR-TRX406-HD-V2. The unit replaces the outer portal housings at either front or rear axle positions and is supplied in a black finish as a direct-style upgrade for scale and trail crawler setups.

Fitment intent: the housing suits TRX-4 portal axles that accept outer portal cases, offering a heavier-duty external shell for portal gear installations. It is presented as an aftermarket replacement part rather than a full axle assembly, so confirm your axle variant supports an outer portal housing before ordering.

Installation and tuning: this is a direct-replacement style component. You will typically move internal items such as bearings and seals from the original housing into this unit. Recheck axle alignment and torque values after assembly. Use within scale or trail-focused builds where the outer case changes clearance and driveline height.

This outer portal drive housing is offered as a heavy-duty replacement choice for TRX-4 portal axle projects, aimed at builders prioritizing scale trail performance and greater exterior durability improvements.

How do I confirm my TRX-4 axle accepts an outer portal housing?

Inspect your axle housing layout and mounting points; this unit requires the outer case style used by TRX-4 portal axle variants. Compare bolt patterns and clearances before purchase.

Are bearings and seals included with the housing?

No. This housing is sold as the external case only; plan to transfer bearings, seals, and any internal components from your existing housings unless otherwise stated by your supplier.

Can I paint or refinish the black surface?

Yes, the surface can be refinished, but test paint adhesion on a spare area and avoid thick coatings that could interfere with fit or clearances around fasteners.

Will this change gear ratios or driveline geometry?

The housing itself replaces the outer case and may alter clearance and driveline height, but it does not change internal gear ratios unless you also fit different portal gears inside the housing.
