These offset hex adaptors allow you to drastically change the track width of your crawler. By increasing the trackwidth, the stability of your truck or rig will be increased as it will prevent it from toppling over on inclined climb spots! By increasing the trackwidth, your chassis flex is also increased due to a leverage effect of being able to put more force on the outter wheel which translates to more grip during climbs! Note: This will fit wheels with a center hole of at least 5mm.
