Traxxas TRX-4 Outer Portal Housing Replacement, Gun Metal - JR-TRX406-GU by Jazrider  [JR-TRX406-GU]

Gun metal aluminium outer portal housing for TRX-4

This item is an RC-scale outer portal drive housing made for Traxxas TRX-4 scale and trail crawler vehicles. The part is machined from aluminium and finished in gun metal to serve as the front or rear outer portal housing, offering a direct swap option for worn or broken plastic housings while keeping the original portal geometry intact.

Its main function is protective: the aluminium outer shell covers the portal assembly and helps maintain correct wheel offset and axle alignment when used as a direct replacement on TRX-4 portal components. It also provides a metal exterior that resists scuffs and pairs well with other aluminium upgrades on the model.

Installation is intended for those familiar with TRX-4 servicing: remove wheel and existing outer housing following standard procedure, place the aluminium shell in position of the original cover, and secure with the factory fasteners. Adhere to Traxxas recommendations for fastener torque and bearing retention, and check for adequate clearance before running.
