Axial Racing RR10 Bomber 21mm Wheel Hex Adapter Upgrade Aluminium RR010/215 by GPM  [RR010/215]

Track widening hex adapters for RR10 Bomber

This aluminium pair of wheel hex adapters is designed to push the wheel stance of the Axial Racing RR10 Bomber wider for improved lateral stability on challenging terrain. The kit yields a 21mm combined offset so wheels sit further apart for better balance on obstacles.

The adapters accept wheels with a 5mm centre hole and are intended for 4mm threaded wheel shafts when dimensions are compatible. Retention uses an o-ring, spring steel ring, springs plus washers, stainless steel screws and a Delrin collar to keep the hex located and limit unwanted wheel rotation under load.

Fitting is straightforward for most hobbyists: slide the adapter onto the shaft, position the Delrin collar, add the spring and washers, secure with supplied screws and pins, and check wheel runout before the first trail. These are for tuning track width and wheel clearance rather than reworking drivetrain components.
