Hendrickson International Corporation, acquired by The Boler Company in 1978, started manufacturing commercial trucks in 1913 to meet the demand for robust and durable vehicles. The company introduced the first tandem suspension in 1926. From the beginning, Hendrickson's only business has been to serve the needs of the commercial vehicle industry. That focus is the key to its status as the world leader in the design and manufacture of high quality truck, tractor, and trailer suspensions, liftable suspensions, steel leaf springs, bumpers, and stamped components for the heavy-duty transportation market. The core capabilities of Hendrickson's operating divisions range from computer-aided engineering and prototype testing to CNC machining and synchronous flow manufacturing. Hendrickson is a major supplier to every North American heavy-duty truck and trailer original equipment manufacturer, as well as many manufacturers in Europe, Australia, Mexico, Japan and Latin America.
