ULTIMATE CALLOUT CHALLENGE 2022

One of the biggest events on the diesel performance calendar took place at Indianapolis Motor Speedway Raceway Park! The Ultimate Callout Challenge was an action-packed weekend where competitors were put to the test on the drag strip, at the dyno, and in a sled pull. In addition, there was the UCC Show and Shine, where builds of all years, makes, and models came to be shown off by their owners!
