Started in the early 1960s, EFDYN has grown to become a leading supplier of energy absorption products. Over the course of the last 45 years, we have moved from Chicago to our present location of Tulsa, Oklahoma.

EFDYN has always been renown for its manufacturing quality and products of outstanding value. Our eagerness to expand and build upon this reputation drives us to constantly examine and improve our methods and processes to insure that we continue to provide our customers with superior products and service.
