Dorman Products, Inc.
A maker of replacement and upgrade parts for cars, trucks, and specialty vehicles like ATVs, sold under brands including Dorman, Dayton Parts, SuperATV, and OE FIX to drivers and repair shops across North America. The company grew out of a business begun in 1918 by brothers Jack and Lew Dorman in Cincinnati, who hunted down hard-to-find auto hardware; in 1994 it merged with a similar Philadelphia venture founded by two other brothers. Fun fact: its HELP! line solves everyday headaches—like a missing clip or a broken plastic part—with ready-made fixes for mechanics and weekend DIYers alike.
