Traxxas TRX-4 Compatible Portal Drive Housing, Machined Aluminium - JR-TRX406-GU by Jazrider  [JR-TRX406-GU]

Machined outer portal housing suited to TRX-4

This replacement outer portal drive housing is made for Traxxas TRX-4 scale and trail crawler platforms. The part is a gun metal finished machined aluminium outer shell, specified to serve as a front or rear outer portal housing to swap in for worn plastic pieces while preserving the portal axle geometry of the model.

As a component it provides a durable outer cover for the portal assembly, helping to maintain accurate wheel offset and axle alignment when fitted as a direct replacement on compatible TRX-4 portal units. It is practical when you need a metal external surface that stands up to abrasion and matches other aluminium upgrades on the vehicle.

Installation is recommended for skilled hobbyists: remove wheel and the factory outer housing using standard TRX-4 service procedures, replace with the aluminium outer shell, and refit the original fasteners to their factory engagement. Follow Traxxas factory guidance for correct fastener seating and bearing retention and verify clearances before operation.
