GPM Axial Racing RR10 Bomber 21mm Aluminium Wheel Hex Adapters RR010/215  [RR010/215]

Wheel hex adaptors to broaden RR10 Bomber track

This pair of aluminium wheel hex adaptors is a scale accessory intended to widen the wheel stance on the Axial Racing RR10 Bomber, providing a 21mm total offset so the wheels sit further apart and deliver improved lateral stability on technical rock courses.

The adaptors accept wheels with a 5mm centre hole and are designed for use with 4mm threaded wheel shafts where dimensions match. Mechanical retention uses an o-ring, a spring steel ring, springs with washers, stainless screws and a Delrin collar that positions the hex and reduces unwanted rotation of wheel assemblies under load.

Installation is a simple hobby-level task: slide the adaptor on to the shaft, locate the Delrin collar, fit the spring and washers, secure with the supplied stainless screws and pins, and check wheel runout before the first outing. These adaptors are focused on track width and wheel clearance tuning rather than changing drivetrain internals.
