TRAXXAS TRX4 Crawler Wheels Aluminum 6-Pole with 21mm Hex Adapter TRX4689/21MM by GPM  [TRX4689/21MM]

Scale crawler wheel and tyre set for TRX4

This 12pcs wheel and tyre package is an aftermarket, scale-oriented set intended for TRAXXAS TRX4 Trail Crawler use. It combines aluminium 6-pole wheels with crawler-pattern tyres and includes a 21mm hex adapter to mate with TRX4 hubs, aimed at reliable fitment and tuning rather than cosmetic change alone.

The practical design means aluminium hubs provide a firmer mounting face than common plastic wheels, while the crawler tyres concentrate on low-speed traction and controlled slip for technical sections. The included 21mm hex adapter suits models accepting that hex size and avoids the need for permanent axle or hub alteration.

Fitting guidance: attach wheels with the vehicle's standard wheel nuts or screws, confirm the adapter is correctly seated prior to driving, and inspect the hub and beadlock areas for clearance. Tweak tyre seating and wheel offset to maintain suspension geometry and prevent contact with chassis components.

Recommended for drivers who want a robust aluminium mounting surface and crawler rubber tuned for slow-speed traction; verify TRX4 hub compatibility before final installation.
