Axial Racing RR10 Bomber Precision Aluminium Wheel Hex Adapter 5mm-12mm 17mm RR010/1217 by GPM  [RR010/1217]

Technical overview of the wheel hex adapter

This aluminium wheel hex adapter is a replacement component intended for Axial Racing RR10 Bomber wheel systems, engineered to match an inner 5mm axle bore and outer 12mm wheel hex so no hub or wheel modification is required. The component forms the mechanical interface between axle output and wheel hex and maintains a compact 17mm thickness for predictable stack height.

Aluminium construction provides greater resistance to deformation than typical plastic hexes, aiding in consistent wheel alignment under operational load. The adapter dimensions are inner 5mm, outer 12mm and 17mm thickness, and the product is provided as a 2pcs set for both sides.

Installation steps: verify axle and wheel hex dimensions match inner 5mm and outer 12mm, slide the adapter onto the axle until flush, then secure the wheel with the original fastening hardware. After assembly inspect for axial play and re-seat components to minimise fitment clearance between hub and wheel.

For setup and tuning the aluminium interface reduces flex at the mounting plane and helps maintain the wheel offset defined by your existing hub and wheel stack. These adapters are intended as a direct replacement for worn plastic hexes or as an upgrade for a firmer mechanical coupling in scale off-road applications.
