Neapco has a heritage that dates back to the invention of the automobile. The New England Auto Products Corporation adopted the trademark of Neapco in 1924. Its principal products were universal joints. In the mid-1930s, the company added a line of agricultural joints and shafts and Neapco became a key supplier to the farm implement market. The company also contributed to the country s defense effort during World War II when it became a supplier of projectiles and pin and block universal joints to the U.S. Navy. In the late 1940s, a line of industrial joints and shafts was added to the existing line of universal joints for cars and light trucks. In 1966, the product line was further expanded to include heavy-duty driveline components, such as large universal joints for over-the-highway trucks. In 2003, the Carlyle Group, a private investment firm, acquired Neapco from the umbrella corporation UIS. Neapco maintains a location in Pottstown, Pa.
