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 heavy duty pickup on the road, the fastest way to get the right part the first time is to start from the exact model year. GMT900 HD through 2014, K2XX HD from 2015 to 2019, and the T1XX HD from 2020.
The parts we ship most for the 2023 GMC Sierra 2500 HD are steering linkage and drag links, brake rotors and calipers, turbo and charge air components, fuel injectors and lines and glow plugs and controllers. These are genuine GM parts, engineered by the team that built the vehicle and held to the tolerances the original calibration assumed. 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.
If you are replacing a part that failed early, it is worth checking whether GM issued a revised version. Quite a few components carry an updated part number that supersedes the original, and ordering by the old number without checking means installing the same design that already failed once.
The 2023 model year falls inside an established production run. Most part numbers had settled by then, but drivetrain and package choices still divide the catalog. Diesel and gas trucks share a badge and very little else through the cooling, exhaust and fuel systems.
Run your VIN before ordering. It takes a few seconds and it is the difference between installing the part and shipping it back. We ship from Dallas, and in stock orders placed by 2pm Central usually go out the same business day. If you are servicing more than one vehicle from that year, our 2023 GMC 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.
