This GPM kit provides aluminum 17mm hex adapters designed for use on TRAXXAS TRX4 Trail Crawler scale models to widen the wheel stance and improve handling for trail crawling setups. The adapters use a self-lock design intended to keep the wheel secure during steering and low-speed rock crawling.
The set is offered as a 20pcs kit and is intended only for wheels that accept a 17mm hex. It cannot be fitted to original wheels that do not have a 17mm hex interface. The parts feature a CNC-style finish for a clean, aftermarket look and are supplied with the basic mounting hardware shown below.
Use these adapters to increase track width for improved low-speed stability and tighter wheel retention during crawling maneuvers; confirm your wheels accept a 17mm hex before fitting and retain the supplied hardware for secure assembly.
