Extended portal stub axle for trail tuning

This RC-scale steel extended portal stub axle is designed for Traxxas TRX-4 scale and trail crawler platforms. The piece gives a 5mm offset and comes as a set of 4 pcs, using model number JR-TRX416-BK. It replaces the stock stub axles on portal-equipped TRX-4s to change wheel offset and free up room for larger tyres and obstacle clearance without modifying the axle housing.

Fitment guidance: check hub bore and bearing seating before final assembly, confirm thread engagement and endplay, and perform a steering sweep test following installation. Note that offset changes will influence scrub radius and track width; make incremental tuning adjustments to suspension and tyre selection to refine handling.

How does the 5mm offset change handling?

A 5mm offset shifts track and scrub radius, which can improve clearance but may require suspension and toe adjustments to maintain predictable steering.

Should I retune shocks after fitting these?

After fitting, re-evaluate ride height and damping since altered track geometry can change weight distribution; small incremental changes are advised.

Any tyre size recommendations with the offset?

Larger tyres benefit from the extra clearance but check inner fender and axle housing clearance first; trial fit tyres before longer runs.
