“I’ve been working with DEX Heavy Duty Parts for over 10 years, and my experience has been nothing short of excellent. DEX offers a great selection of parts, backed by a knowledgeable and helpful staff. Their website provides detailed descriptions and clear photos, making it easy to find what we need.

The quality and reliability of the parts have consistently exceeded our expectations. In particular, the painted parts we purchase have significantly reduced downtime for many of our customers. DEX’s customer service team is always supportive and ensures the ordering process is smooth and efficient, with parts delivered on time and in excellent condition.
Compared to OEM and other aftermarket suppliers, DEX provides exceptional value in both pricing and quality. Major components like cabs and hoods from DEX have saved our customers both money and time, especially when OEM lead times are long.

I highly recommend DEX to anyone in the industry. If you don’t find what you’re looking for on their website, just call their customer service line—they’re always adding new inventory that may not yet be listed. DEX has become a crucial partner for our business, giving us an additional reliable option to meet our customers’ needs.”

DEX is incredibly easy to do business with, and the parts always arrive as described — no surprises, no issues. What truly sets DEX apart, though, is their people. Brice Holland has been an essential part of our partnership; he’s attentive, responsive, and genuinely committed to our success. Using DEX parts has helped us reduce downtime and offer aggressive pricing to our end users, making it an easy win all around. Their painted and OE-quality renovated parts perform reliably, and we’ve never had problems with anything we’ve received.

Central Transport helps to build and shape the United States by transporting the goods businesses need to run, and the items used by Americans daily. These services are critical to us and our customers, and we believe DEX Heavy Duty Parts understands that better than anyone. As head of procurement, my job is to keep our trucks on the road with as minimal downtime as possible. Having DEX available as a resource for getting factory built, pre-painted parts, makes my job much easier, and minimizes the hassle of a body shop. Without them, our trucks would be down for weeks. Now with DEX parts our trucks are back on the road within a week. This is now the 6th fully dressed hood they have sent me to help get my team back on the road within a few days. I could not be anymore pleased with their products & their team!
