This set of aluminium wheel hex adapters is aimed at increasing track width on AXIAL Racing RR10 Bomber scale crawlers while retaining a compact hub layout. The adapters deliver a 27mm span to move the wheel mounting point outward and help reduce body roll on uneven rock gardens.
They accept wheels with a 5mm centre bore and mount on 4mm threaded wheel shafts where hub dimensions match. The internal assembly comprises a Delrin collar for location, an o-ring on one face and a spring steel retention ring, with a spring, washers and a stainless screw on the opposite face to guard against loosening under load.
Prior to fitting confirm wheel bore and shaft thread, assemble using the supplied hardware and check wheel runout after tightening. These adapters are suited to crawling and trail tuning where a modest track increase improves tyre contact and lateral grip.
