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

Precision 21mm hex adapters for TRX4 applications

This 20pcs set of aluminum hex adapters is engineered as an RC-scale upgrade compatible with TRAXXAS TRX4 trail crawler platforms. The 21mm thickness delivers repeatable wheel offset for improved tyre and rim clearance while maintaining stock suspension geometry, and the aluminium construction is selected for durability under frequent wheel changes.

Intended uses include measured wheel spacing adjustments, clearance solutions for beadlock tyres and wider rims, and minor track-width tuning on scale crawler builds. These adapters are direct replacements for factory hexes when a fixed spacer is required for low-clearance or modified setups.

Installation follows standard wheel removal and replacement procedures; fit the adapters in place of the stock hexes and secure wheels with the usual hardware. Supplied as a 20pcs kit for full-vehicle application or for multiple builds, these components are specified as aftermarket accessories for RC use.
