This is a pack of Hot Racing 12mm to 17mm Hex Hub Adapters, with a 6mm offset. These adapters are compatible with many 1/10th scale vehicles with factory 12mm hex hubs and allow the use of 17mm hex wheels, all while adding a 6mm width extension per side of the vehicle for a wider, more stable, stance.
Total length: 20mm
Max axle diameter: 5mm
Axle thread: M4
Hex depth: 5mm
Comments: See Hot Racing HRARSSLF117X for replacement/spare M4 axle hub nuts; O-rings are 11x1mm.
NOTE: These adapters fix a wide array of vehicles. Make sure the vehicle uses a hex at least 5mm thick, or the adapter may bind against the hub.
