Select The Year Of Your Vehicle Below
The GMC Sierra 1500 started in 1999 and remains in production. GMT900 through 2013, K2XX from 2014 to 2018, and the T1XX from 2019 with the CarbonPro bed option. 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.
A half-ton pickup can show four or five nearly identical brackets, sensors or harnesses depending on cab configuration and build date, and only one is correct. Everything on this page is a factory GM part, built to the original specification and carrying the original part number.
The parts we move most on the GMC Sierra 1500 are brake rotors and pads, fuel pump modules, window regulators, outside door handles and tailgate hardware and cables. On a light 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. 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 3pm Central typically leave our Dallas warehouse the same day, so most of the country sees short transit times. The GMC C1500 Pickup is the nearest alternative in the range if you are comparing parts across models.
