Extended portal stub axle for TRX-4 platforms

This RC-scale steel extended portal stub axle is made for the Traxxas TRX-4 scale and trail crawler chassis. The unit provides a 5mm offset and is supplied as a set of 4 pcs, under model JR-TRX416-BK. It replaces the stock stub axles on TRX-4 portal setups to alter wheel offset and create extra clearance for larger tyres and obstacles while keeping the original axle housing intact.

Installation guidance: verify hub and bearing fit before final assembly, confirm correct thread engagement and endplay, and run a full steering sweep test once fitted. Because offset changes affect scrub radius and track, adjust suspension and tyre choices in small steps during tuning and re-evaluate handling after each change.

Will these fit standard TRX-4 portals?

They are designed for TRX-4 portal axle configurations; confirm bearing and hub fit on your specific assembly before final installation.

How should I approach setup after changing offset?

Make incremental suspension and tyre adjustments, check toe and camber, and test handling progressively to find the desired balance after adding offset.

What basic checks are essential during installation?

Inspect bearing seating, verify clearance for full steering lock, ensure secure thread engagement, and confirm endplay to avoid premature wear.
