About Tri-Power Trading Company

From 1986 to 2006, the three brothers, Robert, John, and Don, owned and operated a successful engine machine shop in Duluth, MN. In 2006, they sold that business and started Tri-Power Trading Co., Inc.

Tri-Power is dedicated to providing quality products that result in increased productivity, while reducing maintenance costs for our customers. New products will continually be added to our offerings as long as these components meet OE-standard quality and reliability, while adding value for our customers.
