This GPM hex adapter is produced as an aftermarket replacement for the TAMIYA T3-01 DANCING RIDER rear wheel hex, designed to connect the rear axle and the wheel with reduced play. The part is machined from light, high tensile T6 aluminum to keep weight low while providing a firmer interface between wheel and hub.
The adapter converts the original hex to a standard 12mm hex and adds 3mm thickness compared with the original, widening the rear track to improve lateral stability. The hex body thickness measures 10.5mm and the package includes stainless steel flat head screws and washers to secure the wheel to the adapter.
Use this adapter when you want a tighter fit between wheel and hub or a slightly wider rear stance for tuning handling on-track. Installation requires standard hex screw tools and basic wheel removal, and it is intended for RC-scale application only.
