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

21mm aluminum wheel hex for TRX4 setups

This 20pcs set of aluminum hex adapters is an RC-scale accessory intended for TRAXXAS TRX4 trail crawler platforms. The 21mm thickness provides additional wheel offset to gain tyre clearance and improve fitment without changing suspension geometry, while the aluminum construction offers a good balance of stiffness and wear resistance for repeated wheel swaps.

Primary uses include adjusting wheel spacing, creating clearance for beadlock tyres or wider rims, and fine-tuning track width on scale crawler rigs. These adapters replace stock hexes when you need a fixed spacer for low-clearance bodies or wider wheel setups.

Fitting is simple: remove the stock wheel hexes and install these adapters in their place, securing wheels in the normal way. Supplied as a 20pcs kit for complete vehicle coverage, they are sold strictly as aftermarket RC-scale components.
