TRX4 Wheel Hex Spacers 21mm TRX4010/21MM by GPM  [TRX4010/21MM]

21mm hex adapters for scale crawling

This 20pcs set of aluminium hex adapters is made as an RC-scale part for TRAXXAS TRX4 trail crawler platforms. The 21mm thickness gives a useful wheel offset to free up tyre clearance while maintaining original suspension geometry, and the aluminium build helps resist wear during repeated tyre and wheel changes.

Use these adapters where you need extra spacing for beadlock tyres, wider rims or tight body mounts. They act as direct replacements for the stock hexes and provide a straightforward way to adjust wheel placement on low-clearance crawler builds.

Installation is basic: remove the existing wheel hexes and fit these adapters, then secure wheels in the usual manner. The 20pcs supply covers a full vehicle or multiple projects and is offered as an aftermarket RC component only.
