Jim Koehler: Full Biography
Jim Koehler is an American monster truck owner and driver from Columbus, Michigan. He built the Avenger monster truck in 1997 and has driven it ever since, winning the Monster Jam World Finals freestyle championship in 2003 and 2011.
Avenger He built the truck himself, which he has called one of the things he is proudest of. The first Avenger ran a forest green Chevrolet S10 body on a teal chassis; the 1957 Chevrolet Bel-Air body that the truck is known for came later. Avenger is the lead truck of Team Scream Racing, the operation Koehler founded, which also runs Brutus, Mega-Bite and others.
Mr. Excitement The nickname came from fellow driver Scott Douglass and stuck because of how he drives. He took the World Finals freestyle title in 2003, the first driver to win it who was not called Dennis Anderson or Tom Meents, and Monster Jam has given him the Extreme Air award seven times.
Every Finals A second freestyle championship followed in 2011, won on a tie-break against Cam McQueen. He won the freestyle title at the Australian finals in 2009 and again in 2010. He has raced at every Monster Jam World Finals held, and in 2025 he was inducted into the International Monster Truck Hall of Fame.
