The commitment to quality started by Lyle Burgess continues today. Thousands of parts are designed, engineered and manufactured in the USA at the company's Stockton, California facility. Rare Parts stocks the available product lines from Moog, Mcquay-Norris, TRW and more. When a part goes obsolete, or has never been available in the aftermarket, then Rare Parts uses its full in-house machine shop and testing facility to design, test and manufacture it.
