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

9mm brass adapters for better crawling stability

This set of 9mm brass wheel hex adapters is made for TRAXXAS TRX4 Trail Crawler use to widen track and increase rotational mass for steadier low speed performance. Each brass adapter measures 9mm in thickness, about 4mm more than the stock hex, and each unit weighs roughly 6g as supplied.

Using wider hexes narrows the lateral gap between wheel and hub on TRX4 platforms and moves the wheel outward without modifying suspension geometry. The design focuses on wheel fitment and tuning for TRX4 Trail Crawler models and the package includes hardware to mount the adapters to standard wheel hex locations.

Typical installation: remove the wheel, replace the stock hex with the brass adapter, and refit the wheel using the provided fasteners, checking clearance and secure seating before running. This ensures safe RC-scale operation after the upgrade.
