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

25mm track-widening wheel hex for RR10 Bomber

This RC-scale wheel hex adapter set is purpose made for use with the AXIAL RR10 Bomber platform, widening wheel spacing by 25mm total to enhance lateral stability on technical crawler lines. The adapters accept wheels with a 5mm hub hole and are designed to mount on 4mm threaded wheel shafts, letting you change track width without altering hub geometry.

The kit uses an internal Delrin locating collar to centre the hex on the shaft, an O-ring on one face to provide preload, and a spring steel retaining ring with spring and washers plus a stainless steel screw to secure the assembly under heavy traction. Those hardware features reduce wheel slip on the hex during demanding crawls while keeping the unit serviceable for routine inspection and adjustment.
