Critical to keeping your equipment performing is parts availability. Thompson Machinery proudly serves Tennessee and Mississippi, offering a wide range of Cat parts solutions—including filters, hydraulic parts, engine parts, undercarriage parts, ground engaging tools, electrical components, and seals and gaskets—to our customers. New Caterpillar parts can be purchased from all of our facilities. For quality, reliability and availability, you can’t beat our Caterpillar parts near you. If machine downtime is critical, a customer may choose to buy a Thompson Exchange component. In certain situations, a used part may be the best solution, and we carry an extensive line of used, unused and reconditioned items for Caterpillar equipment. Thompson has the best parts solutions to meet your needs of quality, availability and price.
