Mack trucks are built to last, but when the time for repair and maintenance comes it’s strongly recommended to use genuine Mack® components. Designed and manufactured according to strict OEM specifications, Mack parts offer the same engineering and performance as their stock equivalent. This ensures a seamless fit, smooth installation, and reliable operation overall. Mack offers a wide range of genuine parts, including engine, exhaust, transmission, cab, and body parts and accessories. It also offers remanufactured components that offer the same good-as-new quality at a more accessible price range. All genuine Mack parts are tested in both the laboratory and field environments to ensure they meet or exceed industry standards.
