That locks in your vehicle so every part we show fits. Genuine GM parts at up to 40% off dealer prices.
If you are keeping a commercial vehicle on the road, the fastest way to get the right part the first time is to start from the exact model year. Cutaway chassis rated above the 3500 for box and shuttle bodies.
The parts we ship most for the 2018 Chevrolet Express 4500 are water pumps, mirror assemblies, headlamp assemblies, upfit body hardware and front hub assemblies. Everything on this page is a factory GM part, built to the original specification and carrying the original part number. On a commercial vehicle these are the components that carry load and heat, and they are where an aftermarket substitute costs you the job twice.
Body and exterior parts are where fitment errors get expensive, because a panel that is close but not correct will not line up with the panels around it. Confirm those against the VIN before ordering rather than after.
2018 is a carryover year for this vehicle. That makes sourcing simpler in the mechanical systems and no simpler at all in trim and body. Upfit configuration, GVWR rating and wheelbase all change part numbers on these chassis.
If you are not certain which version you have, give us the VIN and we will confirm fitment before you check out. In stock orders placed by 2pm Central typically leave our Dallas warehouse the same day, so most of the country sees short transit times. For a different year of the same vehicle, our full Chevrolet Express 4500 catalog lists every year we cover.
We specialize in GM vehicles that are 10 to 15 years old, and we often carry new-in-box parts for older models too. Discontinued parts are a normal part of the OEM business. When GM stops making a part and our stock is gone, that is the end of the line for that OEM part. We thank you in advance for understanding. The GM Parts Club advantage: our massive buying power lets us stock deep on the parts GM owners need, in our huge warehouse in Dallas, Texas.
