AKA HEXlite 1/10 buggy wheels were designed with two things in mind, weight and durability. Both were achieved through superior engineering and use of AKA's proprietary high-impact nylon. This combination makes them one of the lightest hex wheels on the market. Plus, HEXlite wheels spin true and balanced thanks to the "made in the U.S.A" quality craftsmanship. Also, a revolutionary feature to the 1/10 market is the optional wheel stiffener insert (Not Included). It has been designed to stiffen the already stiff wheel, as well as help prevent dirt from building up inside the wheel, which will cause the wheel to go out of balance.
