Limited availability on pre-2010 parts. Factory parts for vehicles older than 2010 are getting harder to source every year. We can still get many of them through GM remaining stock and vintage parts channels, but supply is limited and availability changes without notice. If your part shows in the catalog, order it and we will confirm availability right away, or contact us first and we will check before you buy.

The GMC Sierra 3500 ran from 2001 through 2006. One-ton truck before the HD naming became standard. Because that run covers more than one engineering generation in most cases, the single most important thing you can do before ordering is confirm which year you are working on. Parts that look interchangeable across a nameplate very often are not.

Diesel and gas trucks share a badge and very little else through the cooling, exhaust and fuel systems. These are genuine GM parts, engineered by the team that built the vehicle and held to the tolerances the original calibration assumed.

The parts we move most on the GMC Sierra 3500 are steering linkage and drag links, brake rotors and calipers, turbo and charge air components, fuel injectors and lines and glow plugs and controllers. On a heavy duty pickup these are the components where the difference between a factory part and a discount replacement shows up fastest, because they carry load, heat or both. 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. The GMC C1500 Pickup is the nearest alternative in the range if you are comparing parts across models.
