The Ultimate Callout Challenge 2026 delivered one of the wildest diesel events ever. Massive Cummins-powered trucks battled for horsepower records on the dyno before switching to the sled pull competition.

The highlight of the event was an incredible 3,825 horsepower world record, while several competitors suffered spectacular engine explosions, broken drivetrains, destroyed turbos and catastrophic mechanical failures. One team even swapped an entire truck frame overnight to stay in the competition.
