This aluminium hex adapter set widens the wheel stance on AXIAL RR10 Bomber models by 29mm total, helping the crawler resist roll and hold better on angled rock faces.
Fit depends on wheel hub and shaft dimensions: the hexes accept wheels with a 5mm hub opening and are designed for 4mm threaded wheel shafts. Always confirm those dimensions on your model before fitting.
The assembly uses multiple retention elements to lock the hex in place: an O-ring on one side and a spring steel ring, spring with washers, and stainless steel screw on the other, plus a Delrin collar to stop the wheel from moving on the adapter during high-traction manoeuvres.
Installation advice: line up wheel and shaft, verify the 5mm and 4mm sizes, and tighten the supplied hardware to achieve a secure fit without over-tightening. Run a short test to confirm steering response and clearance after installation.
