Our Story



International Engineering and Manufacturing, Inc. (IEM), established in 1968 in Hope, Michigan, is known worldwide as the industry's premier producer of snowmobile performance and safety traction products for rubber tracks.

In the mid-sixties, the snowmobile industry was experiencing incredible growth, particularly in racing. For James Musselman and his partner, Woody Kozlow, snowmobiling represented the key to future success. At the time, racers used three corner files attached to ski bottoms in an effort to carve ice to maintain control of the snowmobile and win oval races. Using their knowledge of carbide wear characteristics and by developing a process to attach the carbide to a metal base, they developed the first pair of carbide runners and delivered them to local racer, Dana Wiltse. Those runners proved to be a handling breakthrough and soon racers throughout the region wanted a pair of "Woody's" runners.

Soon a star for the track was added to the Woody's line followed by a carbide tipped device to install in the track. Another handling breakthrough for the racers, it didn't take long for the carbide tipped traction devices named studs to become essential for racers and the norm for recreational snowmobile riders.

From this beginning, the Musselman family transformed IEM from a part-time business to an international corporation. Under the leadership of second generation family members, Robert Musselman, President and Mark Musselman, Vice President, they credit their expansion to perseverance, hard work, innovation, and an unwavering commitment to quality products.

Woody's, the trademarked name of IEM's private label traction devices, is synonymous with quality in snowmobile accessories and is as recognizable as the snowmobile Original Equipment Manufacturers wherever people ride snowmobiles. Woody's is the choice worldwide of motorsports accessory distributors, snowmobile and track manufacturers, off-road vehicles, racing champions, sportsmen and snowmobilers who want the very best in traction performance and safety.

IEM products are manufactured in the U.S.A.
