Ultimate Callout Challenge 2021 with FASS Motorsports

May 24, 2021

UCC 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!
