The Harris Clash is an annual racing event held in early August. The event is sanctioned by IMCA and promoted by Bob Harris Enterprises. It is widely regarded as being one of the best IMCA modified races in the country, drawing hundreds of cars and thousands of fans every year.
The Harris Clash was started in 1992 by Bob Harris of the Harris Auto Racing Company (current owner of Bob Harris Enterprises) as a challenge to other racing chassis manufacturers. Not only is the winning driver of the race given national recognition, but unlike other major events, the car manufacturer is also given major exposure. In 2015, the event included two classes: IMCA Modifieds and IMCA SportMods (which is an entry-level modified division). The IMCA Late Models are no longer included in the Harris Clash event. In late 2024, it was announced that the 2025 Harris Clash would add the IMCA Stock .
