GPM AXIAL RR010/255 RR10 Bomber 25mm Aluminium Wheel Hex Adapters  [RR010/255]

Precision wheel hex adapters for RR10 Bomber

This adapter set is engineered for the AXIAL RR10 Bomber platform to increase track width by 25mm for improved lateral stability on crawler courses. The parts accept wheels with a 5mm hub bore and are machined to locate on 4mm threaded wheel shafts, enabling a robust track-width change without hub modification.

The assemblies include a Delrin locating collar for concentric shaft alignment, an O-ring on the mating face to provide controlled preload, and a spring steel retaining ring with spring and washers plus a stainless steel screw to secure the stack. These engineered retention elements reduce slip at the hex interface under heavy torque while remaining serviceable for inspection and adjustment.
