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

Product summary for hex adapter

This aluminium wheel hex adapter is a scale replacement designed for Axial Racing RR10 Bomber wheel assemblies, matching an inner 5mm axle bore and outer 12mm wheel hex so hubs and wheels remain unchanged. It acts as the interface from axle output to wheel hex while keeping the assembly thickness to 17mm.

Made from aluminium to resist distortion compared with basic plastic hexes, the adapter helps maintain wheel alignment under load. The specified measurements are inner 5mm, outer 12mm and 17mm thickness, and the product is supplied as a two piece set.

Fitting is straightforward: check that your axle and wheel hex match the inner 5mm and outer 12mm, slide the adapter onto the axle until it seats flush, then secure the wheel with the original fasteners. Inspect for axial play after fitting and adjust the seating to minimise any slack between the hub and wheel.

When tuning, the aluminium hex adapter stiffens the wheel-to-axle joint, reducing flex at the mount and helping preserve the wheel offset that your existing hub and wheel stack set. These adapters are useful when upgrading worn plastic hexes or when a firmer mechanical coupling is desired for scale off-road driving.
