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

Hex adapter quick overview

This aluminium wheel hex adapter is a scale replacement part designed for Axial Racing RR10 Bomber wheel setups, matching the inner 5mm axle bore and outer 12mm wheel hex without modifying existing hubs or wheels. It serves as the mechanical link between the axle output and the wheel hex while keeping the assembly compact at a 17mm thickness.

Constructed from aluminium to resist deformation compared with basic plastic hexes, the adapter helps maintain wheel alignment under load. Specified dimensions are inner 5mm, outer 12mm and thickness 17mm, and the item is supplied as a 2pcs set.

Fitting is straightforward: verify your axle diameter and wheel hex sizes match the inner 5mm and outer 12mm, slide the adapter onto the axle until it seats flush, then refit the wheel with the original fastening hardware. After installation check for axial play and re-seat components as needed to minimise slop between hub and wheel.

For setup and tuning this aluminium adapter stabilises the wheel-to-axle connection with a stiffer metal interface, reducing mount flex and preserving the wheel offset from your existing hub and wheel stack. Use these adapters when replacing worn plastic hexes or when you want a firmer mechanical coupling in scale off-road builds.
