It was introduced in 1999 and followed the previous C/K line of trucks from GM. 

You treat your Sierra 3500 HD like the integral part of your business that it is by using genuine OEM parts when you need a replacement part. You can find those parts at

  • Body - Your truck is tough, but that does not mean that the body cannot be damaged from being on the job site or towing heavy loads. If you have a bumper that is damaged or a mirror that has been knocked off, you need to fix the parts. We have those mirrors and bumpers along with fenders, roofs, doors, interior trim pieces, antennas and all other body parts for your truck.
  • Fuel System - At some point, you should change the fuel filter on your truck in order to keep the fuel flowing smoothly to the engine. Additionally, your fuel pump or lines may need to be replaced over time. We have these parts and more like the fuel tank, filler tube, filler cap and more.
