Traxxas TRX-4 Portal Housing Upgrade for Scale Crawlers - JR-TRX406-GU by Jazrider  [JR-TRX406-GU]

Durable aluminium outer portal housing for TRX-4

This is an RC-scale aluminium outer portal drive housing crafted for Traxxas TRX-4 scale and trail crawler models. With a gun metal surface finish, the machined aluminium outer shell is specified as a front/rear outer portal housing to replace damaged or weakened plastic covers while retaining the original portal axle geometry.

The housing functions as a protective external cover for the portal assembly and supports correct wheel offset and axle alignment when installed as a direct replacement on TRX-4 portal setups. It is advantageous for builders wanting a metal exterior that withstands wear and complements other aluminium hop-ups on the vehicle.

Installation is suited to experienced model technicians: follow TRX-4 service steps to remove the wheel and original outer housing, fit the aluminium outer shell into place of the factory cover, and secure using the OEM fasteners. Observe Traxxas guidance on fastener seating and bearing retention and confirm clearances prior to use.
