Why Weller?
We specialize in new and remanufactured heavy duty truck parts, remanufactured transmissions, differentials, steering gears, and driveshafts.
Unmatched Distribution Model
Simply put, our distribution model is second to none in our industry. Unlike our competition, WELLER can get our product to you or your repair facility in less time than any other remanufacturer in the country. Our goal is less down time for you – Same day/Next day. With so many locations to serve you across the United States, we are your source for quality remanufactured heavy-duty driveline components.
Quality Truck Parts
There is a difference between a rebuilt unit and a remanufactured unit. Unlike rebuilt units that have simply had their broken parts replaced, WELLER proudly remanufactures our components through a stringent process of complete disassembly, cleaning, and reassembly with quality inspected components. We remanufacture our units to meet or exceed the Original Equipment Manufacturers’ (OEM) specification. We are proud to say that because of our excellent attention to detail and quality, our warranty rate is the lowest in our history even as we have been growing production. What's more, we will never make you pay more to warranty our product. Can the competition say that?
A Partner You Trust
When you’re trying to keep your customer's trucks on the road, you need a partner you can trust. Weller is driven to be the best in the industry always seeking out ways to improve our processes and partnerships. The fact is, we enjoy our work and we are passionate about providing quality product in stock where and when you need it.
