Avenger is a 1957 Chevy Bel Air monster truck driven by Jim Koehler and is the flagship truck for the Team Scream Racing camp based out of Columbus, Michigan. Avenger is perhaps most famous for its unique bodies which have been ran at every Monster Jam World Finals since 2004. Koehler is the only driver that has competed in every World Finals since 2000.


Avenger was first created in 1997 with a Chevy pickup body in which Jim Koehler campaigned with until after a wild crash in New Orleans 2000, which led to him putting a brand new Chevy S10 body on the truck. This incarnation of Avenger ran until mid 2002 where he created the Nomad/Bel Air body he runs to this day.

In 2002, Jim Koehler debuted a brand new 1957 Chevy Bel Air body for Avenger which was the most successful version of the truck, claiming his first Monster Jam World Freestyle Championship in 2003. Koehler continued to run this version until 2008 when he debuted a new, lighter schemed Avenger and a new chassis.

In 2004, Avenger ran a special orange paint scheme at the Monster Jam World Finals 5. This would start its World Finals tradition wherein the truck runs a special body for every installment of the event. However, in his freestyle run, after his second hit, he bent the four-link bar, causing the transmission to break.

In 2005, Koehler ran a special half dark green and half orange (from last year) paint scheme for Monster Jam World Finals 6, and during his freestyle run, he clipped into the tire of an abandoned Grave Digger on the trailer, causing his run to end. However, he jumped into the pool obstacle after his run. This will start its tradition wherein Koehler jumps into the pool after his run.

In 2006, Koehler ran a chrome paint scheme for Monster Jam World Finals 7, and during his run, he lawn-darted over the pool obstacle.

In 2008, Koehler debuted a more light green version of Avenger on a brand new chassis built by Koehler, while Chris Bergeron received a new chassis built by Pablo Huffaker and Racesource. This truck was more stable and racing oriented than his previous Avenger, but still a freestyle machine at heart, which he proved by winning multiple freestyle events such as Minneapolis 2008.

In 2009, an Australian Avenger debuted. It was also driven by Koehler. It later won the South Pacific World Finals freestyle championship in 2009 and 2010.

In 2011, Koehler won Avenger's second World Freestyle Championship title at the Monster Jam World Finals 12

In 2015 and 2016, Avenger takes part of the Fox Sports 1 Series.

In 2017, Avenger celebrates its 20th anniversary with a special throw-back body that resembles the Chevy S-10 body from 1999-2001. Jim and the truck competes in the East Coast Fox Sports 1 Series. At the World Finals, fans are shocked as Jim and Avenger make it to the semi-finals, but lost to Ryan Anderson and Son-uva Digger. Jim would also get third place in freestyle.

Avenger with it's Chevy S-10 body, for the 20th Anniversary tour

 A brand new chassis, built by Cory Rummell, is debuted at the World Finals and Jim has his longest run in the racing bracket, going all the way to the semi-finals. The 2008 chassis becomes Wrecking Crew/Axe.

In 2018, Jim competed in one of the Monster Jam Stadium Tours with the original Bel Air body back. Jim drove Avenger at the Monster Jam World Finals 19, where he crashed on his first hit. He brought the blue Bel Air body back for the Wildwood, NJ show, taking 2nd place overall.


  • With its first championship at World Finals 4, Avenger is the only truck to finish last place both the year immediately proceeding and following the same year winning a championship (in the case of the latter, tying last with Blue Thunder and Team Suzuki at Monster Jam World Finals 5).
  • Avenger is the only truck to compete at every single Monster Jam World Finals (including the Motor Madness World Finals "0") while being driven by the same driver.
  • Avenger has won the "Extreme Air of the Year" at the World Finals 6 years in a row from 2011-2017. The streak would be ended by Rosalee Ramer (Wild Flower) in 2018.
  • "Avenger" was also the name of Jim Koehler's Dad's Drag Racing car, and Jim decided to continue the Avenger name by naming his monster truck after his car.
  • Now retired Corey Clark drove the truck a few times in Australia.
  • YouTube ganged some minor controversy in 2016 after several amateur videos of Avenger's World Finals 17 freestyle were muted out due to copyright reasons due to the song that was playing during Avenger's freestyle. At least six videos were muted out by YouTube. One of these videos was a full freestyle compilation uploaded by YouTube user TLITD31. When the video was originally uploaded, YouTube muted the entire video solely due to Avenger's freestyle, so the user had to re-upload the video with Avenger's freestyle clip self-muted out. The blocked out song was Let Me Hear You Scream by Ozzy Osbourne.
  • Avenger was the first ever non-FELD owned truck to win a World Finals championship. Jim Koehler won the freestyle championship at Monster Jam World Finals 4.
    • On top of this, Avenger is the only Non-FELD truck to win more than one World Finals Championship.

BKT Tires "I WISH" at the World Finals 16

  • At the Monster Jam World Finals 16, Avenger had an onboard shot of the chassis, with a BKT sticker in front for sponsorship purposes. Jim didn't have BKT tires on the truck yet, and as some funny humor, next to the BKT sticker, he wrote "I WISH".
