FaqRules & Guidelines

YOU MUST CONTACT COLE DIRECTLY TO ENTER YOUR TRUCK IN THE STREET TRUCK CHALLENGE. CALL OR TEXT 260-414-0082 OR EMAIL [email protected]

This competition will be geared towards street driven trucks. This is our first year so it’s going to be a learning process for all of us. We will try to be lenient to a certain extent. Our main goal here is to put on a great show and have fun! Entry fee will be $200. We are taking 10 entries for the diesel class. These entries will be first come first serve. Once the 10 spots are filled and paid for there will be no additional entries and no waiting list. If a competitor drops out at anytime, no refund will be given and we will not fill that spot. Competing order for all 3 events will be determined by random draw. The points leader after the 3 events will be the overall champion. The winner will take home $2,000 cash and will be entered free of charge into the 2026 STC challenge to defend his/her title. The STC staff will have the final say on any discrepancies.
