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.
It was announced that the 2018 Harris Clash would be held at the Deer Creek Speedway, in Spring Valley, MN. The 2018 event will be the first IMCA race held at the track.
