For more than 30 years DENSO Commercial & Heavy Duty has been building the parts that keep the most powerful commercial trucks and equipment operating both on the highway and off. We know that every hour a truck or piece of equipment spends out of commission costs money. That’s why everything we make is built with the highest precision and craftsmanship to exact OE standards. DENSO Heavy Duty manufactures and sells OE quality parts that are made to be durable and dependable so that you don't have to worry about down time.
