These made truck owners who had a passion for the sports to modify their trucks to suit well in the events. The sport also involved car crushing, and this saw concern when a promoter of the events saw a video of Bob Chandler with his monster truck he’d named ‘big foot’ crush vehicles in April 1981.
Truck owners first started creating lifted trucks to take part in such events and they were soon competing on whose truck was the biggest. They did this by increasing the height of their trucks in various ways. The lifting of trucks was mainly done on the truck tires and during that time, monster trucks were running on tires 1.2m in diameter.
Kingkong and Bear foot were constructed after Big Foot to 1.7-meter tires, and soon other monster trucks, e.g., King Krunch, Virginia Giant, and Maddog were being constructed.
These trucks were mainly built off heavily reinforced stock chassis, used leaf spring suspension, a stocky body and military axles that are also heavy, and they were to give support to the tires. Till the 1980s, these trucks were mainly used to perform exhibitions showing mud bogging events.In 1985, monster trucks started being used in racing events. These events are still done today.
These racing events led to the construction of lighter trucks with more powerful engines and also the introduction of rules for the constructions and truck safety. Such rules were started by the Monster Truck Racing Association (MTRA) which was formed by Bob Chandler, Braden and George Carpenter in 1988. Recent years have seen the evolution of trucks from using leaf springs to coil springs.
