If you are keeping a light duty pickup on the road, the fastest way to get the right part the first time is to start from the exact model year. GMT900 through 2013, K2XX from 2014 to 2018, and the T1XX from 2019 with the CarbonPro bed option.
2012 is a carryover year for this vehicle. That makes sourcing simpler in the mechanical systems and no simpler at all in trim and body. 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.
The parts we ship most for the 2012 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.
The catalog is organized by assembly group rather than by symptom, which trips people up. If you know what failed but not what it is called, give our specialists the symptom and the VIN and they will find the group it lives in.
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. If you are servicing more than one vehicle from that year, our 2012 GMC catalog covers the rest of the lineup.
