GMC Sierra 1500 HD OEM Parts and Accessories

Select The Year Of Your Vehicle Below

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 1500 HD ran from 2001 through 2006. Half-ton badged truck on the heavy duty frame with the 6.0L V8. 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.

Heavy duty trucks split on cab and chassis configuration, single versus dual rear wheels, and gas versus diesel, and the catalog will often show several options for the same nominal part. Every part listed here is a genuine GM component with the factory part number, not an aftermarket reproduction.

The parts we move most on the GMC Sierra 1500 HD are glow plugs and controllers, water pumps and thermostats, exhaust manifolds, transfer case components and fifth wheel and gooseneck hardware. 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. Send us your VIN before you order and our parts specialists will confirm the exact part number for your vehicle.

Orders placed by 3pm Central usually ship the same business day from our Dallas warehouse, which keeps transit times short across most of the country. The GMC C1500 Pickup is the nearest alternative in the range if you are comparing parts across models.
