These MK.8 Wheels are molded from heavy duty nylon for strength and durability. Step-down (3.0/2.2) asymmetrical construction gives them superior handling and realistic looks. The 8 hole center section is shiny chrome with a black outer bead-lock style rim. These are designed for the BLITZ truck and they can also be used on other trucks that use 12mm hex hubs. Sold in pairs.
