TRAXXAS TRX4 Wheel Hex Adapters 9mm Brass Offset and Weight TRX4010X/9M by GPM  [TRX4010X/9M]

Brass 9mm hex adapters for improved stance

These 9mm brass wheel hex adapters are an upgrade option for TRAXXAS TRX4 Trail Crawler platforms that widens wheel stance and increases rotational mass to help with low speed control. Each adapter is brass, 9mm thick, about 4mm thicker than the original hex, and weighs around 6g per piece as supplied.

The wider hex reduces the lateral gap between wheel and hub on TRX4 rigs and pushes the wheel further outboard without changing suspension geometry. The set is intended for wheel tuning and fitment on TRX4 Trail Crawler models and includes the hardware required to mount to standard hex positions.

Fitting is straightforward: remove the wheel, swap the stock hex for the brass adapter, then refit using the included screws and washers. Verify clearance and tight seating as part of a safe installation routine for RC use.
