Ultimate Callout Challenge 2021 with FASS Motorsports
May 24, 2021

UCC DAY 1



UCC Day 1 is a WRAP! Tons of 1,000+ horsepower Cummins, Powerstroke, and Duramax trucks are getting ROWDY on the track. If you’re not here this year, don’t miss out in 2022!

UCC DAY 2


Day two of the Ultimate Callout Challenge 2021 was packed with high-horsepower diesel drag racing, dyno pulls, and a killer show-and-shine! The ODSS drag racing was a hit too, with more fast passes than we could count.


Thanks for watching!
