Feel the mighty power while cruising down the open roads in this magnificent 18-wheeler. Heavy box trucks, or semis, are true works of innovative machine ingenuity and muscle. Not only are these dominating trucks a force to be reckoned with, but the superior design of these towering vehicles has made them the undisputed king of the road. The UGears Canada model includes several moving and fully operational parts and an R6 rubber band motor engine tucked safely under the front hood. The dynamic transmission system allows you to implement three modes: idle, forward, and reverse. Each sophisticated detail is measured and cut using laser precision technology.
