AXIAL Racing RR10 Bomber 27mm Aluminium Wheel Hex Adapters by GPM RR010/275  [RR010/275]

Wheel hex adapters for RR10 Bomber

This pair of aluminium wheel hex adapters is designed to widen track width for AXIAL Racing RR10 Bomber scale RC models while retaining a compact assembly. Each adapter set provides a total span of 27mm, intended to move the wheel mounting point outward to improve lateral stability on technical terrain.

The adapters accept wheels with a 5mm center bore and fit onto 4mm threaded wheel shafts where the wheel hub geometry matches; compatibility depends on matching bore and shaft dimensions. The internal assembly includes a Delrin collar to hold the hex in position, an o‑ring on one side and a spring steel ring, spring with washers and a stainless steel screw on the opposite side to prevent unwanted rotation or loosening under load.

For installation, confirm wheel bore and shaft thread size before fitting, use the supplied hardware to secure the hex, and check wheel runout after tightening. These hex adapters serve a tuning role for crawling and trail setups where a slightly wider track can reduce roll and improve contact on uneven surfaces.
