TRAXXAS TRX4 Brass 9mm Wheel Hex Adapters Track and Mass Tuning TRX4010X/9M by GPM  [TRX4010X/9M]

9mm brass hexes for improved wheel stance

These 9mm brass wheel hex adapters are an aftermarket upgrade aimed at TRAXXAS TRX4 Trail Crawler models to increase track width and add rotational mass for steadier crawling at low speeds. Each adapter is brass, measures 9mm thick and is around 4mm thicker than the stock hex, with an approximate weight of 6g per adapter as supplied.

The wider hex reduces lateral gap between wheel and hub on TRX4 vehicles and positions wheels further outboard without altering suspension geometry. The product is designed for wheel tuning on TRX4 Trail Crawler platforms and ships with the hardware needed to attach to standard wheel hex positions.

To fit, remove the wheel, replace the original hex with the brass adapter and refit the wheel using the supplied screws and washers. Always confirm clearance and secure seating to maintain safe RC-scale operation.
