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. One-ton heavy duty truck in single and dual rear wheel and chassis cab form.
2016 is a carryover year for this vehicle. That makes sourcing simpler in the mechanical systems and no simpler at all in trim and body. 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 2016 GMC Sierra 3500 HD are turbo and charge air components, fuel injectors and lines, glow plugs and controllers, water pumps and thermostats and exhaust manifolds. 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.
Where geography matters is landed cost. A heavy part quoted a few dollars cheaper by an East Coast seller often costs more delivered to the middle of the country than the same part shipped out of Dallas. Compare the total, not the sticker.
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 2016 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.
