Getting parts right on a heavy duty pickup starts with knowing which generation you are working on. One-ton heavy duty truck in single and dual rear wheel and chassis cab form.
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 2013 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.
The parts we ship most for the 2013 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. 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.
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 3pm Central usually go out the same business day. If you are servicing more than one vehicle from that year, our 2013 GMC catalog covers the rest of the lineup.
