The TRX4010/6MM kit is a direct-fit wheel upgrade for TRX4 Trail Crawler vehicles. Four aluminium hex adapters reduce the gap between hub and wheel, moving the wheel closer to the axle for a tidier, more scale offset on rough trails.
Role and fit: these adapters engage with the front CVD and rear drive shaft to the wheel, adding 1mm over the stock hex to produce a 6mm total width. The result is a wider hex face, improved wheel stance and greater low speed stability without changing axle geometry.
Fitment tips: adapters are plug-and-play with stock wheel bolt patterns and come with stainless steel screw shafts for secure installation. Aluminium keeps parts light and resistant to deformation, and several finish options are offered for visual tuning.
