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

Trail-focused wheel and tyre package for TRX4

This 12pcs wheel and tyre set is an aftermarket, scale accessory intended for TRAXXAS TRX4 Trail Crawler rigs. The kit brings together aluminium 6-pole wheels and crawler-style rubber and includes a 21mm hex adapter to fit TRX4 hubs, focusing on practical compatibility and tuning options rather than just looks.

Design priorities are functional: aluminium hubs give a firmer seating surface compared with plastic wheels, and crawler tyres emphasise traction and predictable slip for low-speed crawling. The 21mm hex adapter is provided for models that accept that hex size so you can avoid irreversible changes to axles or hubs.

Assembly advice: use the vehicle's original wheel fasteners, confirm the adapter is fully seated before running, and check for clearance around beadlock hardware or wheel bolts. Adjust tyre seating and wheel offset as needed to keep suspension travel and steering geometry clear of the chassis.

Select this set for a tougher wheel mounting surface and improved crawler rubber performance at slow speeds, and verify hub compatibility on your TRX4 before heading out.
