Traxxas TRX-4 Rear Portal Drive Axle Mount, Aluminum - JR-TRX405-GU by Jazrider  [JR-TRX405-GU]

Gun metal rear portal mount for TRX-4

This RC-scale rear portal drive axle mount fits the Traxxas TRX-4 chassis, finished in gun metal aluminum and produced under the JR-TRX405-GU designation. The part replaces the factory rear axle mounting point with a portal-style drive interface suitable for scale trail and rock crawler builds.

The component secures the portal drive assembly in correct relation to the rear axle housing to help maintain axle alignment under load, offering a metal alternative to standard mounting materials. The machined finish aims to match TRX-4 portal mounting interfaces while preserving a low, scale profile.

Installation notes: confirm fitment against your vehicle's rear portal interface and verify fastener positions before final tightening. Check existing mounting hardware, suspension travel clearances, and wheel offsets. When tuning, treat the mount as part of drivetrain geometry where axle alignment and secure attachment affect traction and drivetrain stress.
