This is a replacement set of aluminum wheels for the Wheelie Bar from Traxxas, designed for use with the Traxxas Wheelie Bar unit. The 6061-T6 aluminum wheels feature an impressive anodized finish and operate with 5x8mm rubber-sealed ball bearings. For controlled and consistent wheelies, Traxxas has developed a durable rubber compound that reduces lateral movement, ensuring stable and consistent wheelies. The tires are available separately and can also be mounted on standard nylon wheels.
