One of the most powerful motorsports events in the country returns to Hendricks County, Indiana, this summer. The Ultimate Callout Challenge (UCC) takes over Lucas Oil Indianapolis Raceway Park June 5–7, bringing three full days of diesel-powered competition, innovation and adrenaline to Brownsburg.
As the premier event in diesel motorsports, UCC draws elite competitors and fans from across North America.
Friday: Drag Racing
The weekend kicks off Friday with drag racing with UCC competitors battling it out on the drag strip in quarter-mile races beginning at 10:30 a.m.
These high-horsepower diesel trucks deliver quick launches and fast passes, but fans can also get in on the excitement by testing their own vehicles on the dyno machine starting at 10 a.m.
Saturday: Dyno Competition, ODSS & Car Show
Saturday brings the high-horsepower dyno competition, as UCC competitors push their trucks to the limit in the second of the three-event contest, which starts at 10:30 a.m.
Meanwhile, the dragstrip will host Outlaw Diesel Super Series (ODSS) qualifying and eliminations throughout the day. More than 500 custom diesel builds will be on display, making it one of the largest Show & Shines in the Midwest.
Sunday: Sled Pull & Awards Ceremony
The weekend wraps up Sunday with the sled pull at 11 a.m., where competitors hook their trucks to a weighted sled and battle for distance.
This intense display of torque and traction is the third and final event for contestants to earn points toward the 2026 UCC title.
