Avenger has taken several titles over the years, but none shine brighter than his two Monster Jam World Finals Freestyle Championships. He won his first world championship title in 2003 with the original Forest Green Bel-Air and teal chassis, Jim shocked the Monster Jam World by being the first Freestyle Champion not named Dennis Anderson or Tom Meents. The following year in 2004 Koehler was stopped on him. He bent a 4-link bar that caused the transmission to break after he went over the cars, causing him to be frustrated. In March 2011, with his red "Las Vegas" Avenger, Jim tied with Cam McQueen in the Nitro Circus Monster Truck in the Freestyle competition, edging out McQueen to claim his second Freestyle title, making Jim Koehler one of only three drivers to have more than one Freestyle title at the World Finals, the others being Tom Meents and Adam Anderson (monster truck driver).

In 2009, Avenger went places that it had never ventured before with the debut of Aussie Avenger, built specifically for the Extreme Monster Trucks Australia tour. This truck featured a bright orange chassis as well as canary yellow rims, with a classic 1957 Chevy Bel-Air body. Jim traveled "Down Under" for the South Pacific Finals where he continued the tradition of American drivers bringing home the Australian championships with his Freestyle victory. In 2010, Jim returned to Brisbane for the South Pacific Finals 3 to defend his Freestyle Championship. "Mr. Excitement" held true to his name by taking a second straight championship in freestyle. In 2016, he is driving in the Fox Sports 1 Championship Series.
