Sourcing parts for a heavy duty pickup comes down to matching the right generation, and that is where most orders go wrong. GMT900 HD through 2014, K2XX HD from 2015 to 2019, and the T1XX HD from 2020.
By 2019 this generation was in steady production, so the catalog is stable, though trim and option content still separate part numbers. GM made running changes mid-year on several heavy duty components, so the correct part can depend on build date rather than model year alone.
The parts we ship most for the 2019 Chevrolet Silverado 2500 HD are transfer case components, fifth wheel and gooseneck hardware, trailer brake controllers, mirror assemblies and tailgate hardware. Everything on this page is a factory GM part, built to the original specification and carrying the original part number. On a heavy duty pickup 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.
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. If you are servicing more than one vehicle from that year, our 2019 Chevrolet catalog covers the rest of the lineup.
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.
