Rear portal mount for TRX-4 applications

This rear portal drive axle mount is intended for the Traxxas TRX-4 chassis and features a gun metal finish, referenced as JR-TRX405-GU. It replaces the rear axle mounting point to accept a portal drive layout for scale and trail use.

The piece locates the portal drive assembly relative to the axle housing to help preserve alignment under load while providing a metal alternative to common stock parts. The profile is designed to align with TRX-4 portal mounting interfaces and maintain a scale appearance.

Fitting advice: verify the rear portal interface and fastener positions before final assembly. Check wheel offset and suspension travel clearance, and confirm mating surface seating. Include this mount in drivetrain checks as alignment and secure attachment influence performance on technical trails.

The mount is made to match TRX-4 portal mounting interfaces, but you should compare bolt patterns and clearances to any portal kit before fitting.
The gun metal finish improves surface durability, but routine maintenance and inspection are recommended for long term exposure to moisture and dirt.
After installation, run a static check of axle runout and driveshaft engagement, then perform a short test drive to detect any binding or unusual noise indicating misalignment.
