Mopar (A portmanteau of Motor and Parts) is the Parts, Service and Customer Care organization within Chrysler Group LLC. Mopar also designs and builds a small number of customized vehicles. The term was first used by Chrysler in the 1920s and was introduced as a brand starting in 1937. Mopar parts are original equipment manufactured parts for Chrysler vehicles. In Canada, these were sold under the Chryco and AutoPar brands until the Mopar brand was phased into that nation's market, starting in the late 1970s.
