At Expert Diesel Parts, we’re a trusted online retailer based in Central California focused on supplying high-quality diesel parts for heavy equipment machinery to customers across the USA and Canada. Whether you’re an independent mechanic, a heavy equipment shop, or a business that depends on uptime, we make it easy to find the parts you need—quickly and reliably.
We started by supplying parts locally and on eBay, helping customers get what they needed with fast service and fair pricing. Over time, demand grew—and so did we. Today, we operate under the Expert Diesel Parts brand, offering a streamlined online experience through our website and serving customers nationwide.
We offer a wide selection of genuine replacement and aftermarket parts, all backed by warranty, and ready to ship from our inventory of hundreds of in-stock items.
