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

Precision aluminium wheel and crawler tyre kit

This 12pcs wheel and tyre set is an aftermarket component engineered for TRAXXAS TRX4 Trail Crawler platforms. The assembly combines CNC-friendly aluminium 6-pole wheels with crawler-pattern rubber and includes a 21mm hex adapter to ensure secure interfacing with compatible TRX4 hubs, with emphasis on mechanical fit and tuning capacity.

Engineering notes: aluminium hubs increase clamping rigidity relative to standard plastic wheels, delivering a stable mounting surface for beadlock or bolted wheel configurations. The crawler tyres are selected for predictable low-speed traction characteristics required by technical crawling, while the 21mm hex adapter allows use on hubs that accept that dimension without modifying axles.

Professional installation guidance: use the vehicle specified wheel fasteners, verify full seating of the 21mm hex adapter under load, and confirm there is no interference with existing beadlocks or wheel hardware. Adjust tyre seating, insert choice, and wheel offset to maintain desired suspension geometry and to prevent contact with shock towers or chassis elements.

Intended for precise aftermarket upgrades where a rigid aluminium mounting surface and dedicated crawler rubber are required; always validate hub and adapter clearance on the TRX4 before installation.
