ABOUT Dennis Kirk Inc.®

We started as a small storefront and snowmobile parts and accessories mail-order business in Rush City, Minnesota, in the heart of the Midwest snowmobile country. Today, still located in Rush City, we fulfill thousands of orders daily from our 200,000 square foot automated distribution center. We currently have over 160,000 items in stock and ready to ship. And when you see our advertising that says we ship today, we mean it. We don't order your parts after you place your order like some of our competitors. If your weekday order is placed by 8pm CST, it is picked, packed and in the truck, on it's way to you, the same day.
