Avenger's history

1996: Jim's dream came true when he finished building the Avenger. The truck was based on a Chevy S-10
1997: He started to compete
1999: Jim and Avenger voted "Fan favorite", which took them to the USHRA first ever World Finals.
2002: Jim felt it was time for a change. He wanted something different. A 1957 Chevy Belair body would replace the standard pickup. The fans feed back was awesome; they love the hot rod monster truck.
2003: Avenger's popularity and Jim's career would hit an all time high after winning the World Freestyle Championship.
