Traxxas TRX-4 Rear Portal Axle Mount Upgrade, Gun Metal Aluminium - JR-TRX405-GU by Jazrider  [JR-TRX405-GU]

Scale-style rear portal axle mount for TRX-4

This RC-scale rear portal drive axle mount is crafted for the Traxxas TRX-4 chassis and finished in gun metal aluminium, listed under the JR-TRX405-GU designation. The item replaces the rear axle mounting location with a portal drive arrangement suitable for scale trail and rock crawling models.

The mount positions the portal drive assembly relative to the rear axle housing to help retain axle alignment under load while providing a robust metal alternative to stock components. The finish and profile are intended to complement TRX-4 portal setups while maintaining a scale look.

Installation tips: check the rear portal interface for fitment and confirm fastener positions before tightening. Review suspension travel clearances and wheel offsets and verify the seating of mating surfaces. Include this mount in your drivetrain setup checks, as it can influence axle alignment and overall handling on technical terrain.
