Genuine GM Parts for the 2015 GMC Yukon XL

Sourcing parts for a full-size SUV comes down to matching the right generation, and that is where most orders go wrong. The extended Yukon, listed without a tonnage suffix from 2015 onward.

One thing worth knowing about buying OEM: the part number ties back to GM's own engineering records, so when a component is revised the supersession is documented rather than guessed at. Aftermarket catalogs have no equivalent, which is why a listing that says it fits a range of years is often wrong at the edges.

The 2015 Yukon XL was in the middle of its production run, so the catalog reflects incremental changes rather than a clean break. Wheelbase and rear suspension design separate these SUVs into groups that look identical from the outside.

The parts we ship most for the 2015 GMC Yukon XL are headlamp and taillamp assemblies, mirror assemblies, water pumps, transfer case components and AC compressors. These are genuine GM parts, engineered by the team that built the vehicle and held to the tolerances the original calibration assumed. On a full-size SUV these are the components that carry load and heat, and they are where an aftermarket substitute costs you the job twice.

Run your VIN before ordering. It takes a few seconds and it is the difference between installing the part and shipping it back. We ship from Dallas, and in stock orders placed by 3pm Central usually go out the same business day. If you are servicing more than one vehicle from that year, our 2015 GMC catalog covers the rest of the lineup.
