Rear portal axle mount engineered for TRX-4

This rear portal drive axle mount fits the Traxxas TRX-4 chassis and is finished in gun metal aluminium, designated JR-TRX405-GU. It replaces the rear axle mounting point to accommodate a portal-style drive assembly for scale trail and rock crawler applications.

The component secures the portal drive relative to the rear axle housing, helping preserve axle alignment when under load and offering a metal upgrade over common stock materials. The design focuses on compatibility with TRX-4 portal mounting interfaces while retaining a scale profile.

Before fitting: verify the rear portal mounting pattern on your vehicle and confirm fastener positions. Check clearance through the full range of suspension travel and review existing mounting hardware for compatibility. Account for this mount when adjusting drivetrain geometry, since alignment and attachment security affect drivetrain behavior on technical sections.

How do I confirm TRX-4 compatibility?

Measure your chassis rear portal mounting pattern and compare bolt hole spacing to the portal kit you intend to use; this ensures the JR-TRX405-GU mount will align correctly.

Will fitting this change handling?

Altering the mount position can affect driveline angles and axle alignment, which in turn may change traction and handling. Check driveshaft alignment and test on familiar terrain after installation.

Should I replace other parts at the same time?

Inspect adjacent mounting hardware, bearings and driveshafts for wear; replacing worn components together helps ensure reliable performance once the aluminium mount is installed.
