18 Rig Parts Inc is part of a family-owned business with more than 13 companies that combined constitute one of the largest distributors of Heavy Duty truck parts in North America. 18 Rig Parts Inc was opened in Houston, Texas in December 2009, but traces its origins to 1953 when the first company, a leaf spring manufacturing plant, was founded.  Over the years, we have diversified our products to become a one stop supplier.  From brakes, to engine parts and air conditioning parts, you can find it all here.
