Mickey Thompson is a title sponsor of the “Mickey Thompson Tough Truck Challenge” where racers will compete for the $10,000 top prize at all 4 Wheel Jamboree Nationals Events. The Mickey Thompson Tough Trucks are split into two divisions, Stock and Modified. Stock division runs for trophies on a single pass format. This class is designed for the “daily drivers” and they must run helmets and some basic safety items. Modified Tough Trucks™ are purpose built 4-wheel drive race vehicles, which must maintain a stock body appearance, and are allowed basic engine modifications. With spectacular jumps and tight corning these off-road trucks are a thrill to watch.
