RockAuto, LLC was founded in Madison, Wisconsin in 1999 by the Taylor family. Their engineering background, passion for old cars, and desire to liberate information hidden behind the auto parts store counter led the Taylors to start RockAuto. Today, RockAuto ships thousands of auto parts from hundreds of manufacturers to customers on every continent except Antarctica-including APO/FPO addresses. The RockAuto catalog is updated daily with mechanical parts like brake pads and shock absorbers, body parts like bumpers and mirrors, interior trim like door handles and carpets, and major assemblies like steering gears, CV axles, engine long blocks, and complete transmissions. There are no mechanics on staff (RockAuto is a store, not a repair shop) but service manuals are available to help customers learn how to perform a repair.
