High-strength portal housing for TRX-4

This outer portal drive housing is formatted for Traxxas TRX-4 portal axle applications and carries the model number JR-TRX406-HD-V2. It replaces the external portal shell at front or rear axles and is supplied in black as an aftermarket housing option for scale and trail crawlers.

Application guidance: suitable for TRX-4 variants that accept detachable outer portal housings. It is intended as a spare or hop-up part rather than a full axle, so confirm axle compatibility before purchase.

Installation reminders: transfer bearings, seals, and other internal components from the original housings as required. After assembly verify axle alignment and torque specifications. Note that swapping outer housings can influence clearance and driveline geometry.

What should I inspect before fitting this housing?

Confirm that your axle uses removable outer portal housings and compare bolt patterns and clearances. Prepare to transfer bearings and seals from the existing unit.

Does this housing come with internal components?

Internal components such as bearings and seals are typically not included; plan to reuse parts from the original housings or source replacements separately.

Are there recommended torque values after installation?

Follow the axle manufacturer's recommended torque specifications for fasteners. Re-torque after initial runs to ensure secure assembly under trail conditions.

Will switching to this housing affect my portal gear alignment?

The external housing changes the casing envelope and can affect driveline alignment; verify internal gear mesh and shaft positioning when assembling to avoid premature wear.
