A nationwide callout to owners and builders of the biggest, baddest, nastiest diesel-powered hot rods on the planet, the Ultimate Callout Challenge brings together the best of the best to battle it out in a drag race, sled pull, and dyno competition.

Spread across three days, the 2021 Amsoil Ultimate Callout Challenge will be held on May 21-23 in Brownsburg, Indiana, at Lucas Oil Raceway. At the end of the event, the scores are calculated to determine the overall UCC Champion!

The best diesel competitors in the world will be on the property to go all-out as they compete in three different categories. The non-stop diesel action gets even hotter with the addition of a show-n-shine as well as 140+ vendors set up at the Diesel Performance Industry Expo at the UCC. Additionally, new for 2021 is the Dan’s Diesel Performance Burnout Pit with $10,000 in prizes going to the top three participants.
