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

Performance wheel and tire set for TRX4

This 12pcs wheel and tire set is an aftermarket, RC-scale upgrade designed for TRAXXAS TRX4 Trail Crawler applications. The package pairs aluminum 6-pole wheels with crawler-style tires and includes a 21mm hex adapter to interface with TRX4 hubs, prioritizing component-level compatibility and tuning flexibility over cosmetic change.

The engineering focus is practical: aluminum wheel hubs give a firmer mounting surface than common plastic wheels, while the crawler tires are tuned for traction at low speed useful in technical trail crawling. The supplied 21mm hex adapter fits models that accept that hex size without forcing permanent modification to the axle or hub assembly.

Installation notes: fit the wheels using your vehicle's standard wheel nuts or screws, confirm the 21mm hex adapter seats fully before running, and inspect the hub interface for clearance with any beadlock rings or wheel hardware. Adjust tire seating and wheel offset as required to preserve suspension geometry and avoid contact with the chassis or shock towers.

Choose this set when you want a more rigid wheel mounting surface and dedicated crawler rubber for improved low-speed traction; always verify TRX4 hub fitment before final assembly.
