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

Wheel hex adapter overview

This aluminium wheel hex adapter is an RC-scale replacement part designed for Axial Racing RR10 Bomber wheel setups, matching the specified inner bore and outer hex dimensions without modifying hubs or wheels. It functions as the interface between axle output and wheel hex, providing a direct mechanical link while keeping the assembly compact at 17mm thickness.

Made from aluminium, the adapter resists deformation compared with basic plastic alternatives and helps maintain wheel alignment under load. The listed dimensions are inner 5mm, outer 12mm and a thickness of 17mm, and the product is supplied as a 2pcs set.

Installation is straightforward: confirm the axle and wheel hex dimensions match the inner 5mm and outer 12mm respectively, slide the adapter onto the axle until it seats flush, then secure the wheel using the original fastening arrangement. Check for axial play after fitting and re-seat as needed to minimise slop between the hub and wheel.

For tuning, this adapter is intended to stabilise the wheel-to-axle connection with a stiffer aluminium interface, which can reduce flex at the mounting point and preserve wheel offset set by your existing hub and wheel stack. Use these adapters when replacing worn plastic hexes or when seeking a firmer mechanical coupling in scale off-road setups.
