TRX4 21mm Aluminium Hex Adapters TRX4010/21MM by GPM  [TRX4010/21MM]

21mm aluminium wheel hexes for TRX4

This 20pcs set of aluminium hex adapters is an RC-scale accessory aimed at TRAXXAS TRX4 trail crawler platforms. At 21mm thickness the adapters provide measurable wheel offset to resolve tyre and body clearance issues while leaving suspension geometry unchanged, and the aluminium construction helps resist wear from repeated wheel swaps.

Use these parts for wheel spacing, tyre clearance and slight track-width tuning on scale crawler builds. They replace the stock hexes where extra offset is required for beadlock tyres, wider rims or low body mounts.

Installation is simple: remove the existing wheel hexes and fit these adapters, then secure wheels in the usual way. The set of 20pcs is suitable for full-vehicle coverage or multiple projects and is offered as an aftermarket RC component.
