Cast metal Hex Wheel Hubs are now available for the RS4 MT line of nitro and electric trucks from HPI Racing. These metal parts replace the stock plastic hubs for a strong and secure wheel mounting system. The cast metal design resists deformation, allowing the wheel nut to be clamped down more firmly than when using plastic hubs. Built-in ribs help grab the wheel for added security. Originally designed to help cope with the extreme power of the 18SS engine in the Nitro RS4 MT 2 18SS kit, these metal hubs are a low cost upgrade to the Nitro MT, Nitro MT 2, electric MT, and can be used on the rear wheels of the Nitro Rush trucks.
