-fits Kyosho and Team Associated 2wd front with 12mm hexes The new 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. Revolutionary to the 1:10 market is the optional wheel stiffener insert. It has been designed to help keep dirt from building up inside the wheel, making it go out of balance, and stiffens the already stiff wheel. HEXlite wheels spin true and balanced thanks to the quality craftsmanship of being made in the U.S.A.
