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 2020 Chevrolet Express 4500 are mirror assemblies, headlamp assemblies, upfit body hardware, front hub assemblies and leaf springs. Every part listed here is a genuine GM component with the factory part number, not an aftermarket reproduction. 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.
One thing worth knowing about buying OEM: the part number ties back to GM's own engineering records, so when a component is revised the supersession is documented rather than guessed at. Aftermarket catalogs have no equivalent, which is why a listing that says it fits a range of years is often wrong at the edges.
The 2020 Express 4500 sits mid-run, which usually means the parts catalog was settled, but option packages and trim still split part numbers within the model year. Upfit configuration, GVWR rating and wheelbase all change part numbers on these chassis.
Send us your VIN before you order and our parts specialists will confirm the exact part number for your vehicle. Orders placed by 2pm Central usually ship the same business day from our Dallas warehouse, which keeps transit times short across most of the country. Parts for the 2019 Express 4500 and the 2021 Express 4500 are listed separately, because the differences between adjacent years are real.
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.
