The catalog for a light duty pickup splits in ways that are not obvious from the outside, which is why the model year matters. GMT900 through 2013, K2XX from 2014 to 2018, and the T1XX from 2019 with the CarbonPro bed option.
The parts we ship most for the 2015 GMC Sierra 1500 are ignition coils, front hub and bearing assemblies, upper and lower control arms, idler and pitman arms and wheel bearings. Everything on this page is a factory GM part, built to the original specification and carrying the original part number. On a light duty pickup these are the components that carry load and heat, and they are where an aftermarket substitute costs you the job twice.
Fitment questions account for roughly a quarter of the OEM orders we handle, and almost all of them trace back to the same cause: one vehicle, several nearly identical parts, one correct answer. The VIN resolves it every time.
By 2015 this generation was in steady production, so the catalog is stable, though trim and option content still separate part numbers. 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.
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. Parts for the 2014 Sierra 1500 and the 2016 Sierra 1500 are listed separately, because the differences between adjacent years are real.
