2013 GMC Yukon XL 2500 Alternators

Genuine GM alternators for the 2013 GMC Yukon XL 2500, at wholesale prices. Alternator output rating varies by electrical load, so a truck with a tow package or upfit wiring takes a different unit. Three-quarter-ton extended Yukon with the heavier frame and the 6.0L V8.

Symptoms to look for

A battery light, dimming headlights at idle, or a no-start after a short drive. On a full-size SUV, suspension type and towing package split this group, and neither is visible from outside the vehicle.

What you get ordering from us

• Factory sourced. These alternators are built to GM's own drawing by the supplier GM contracted.
• No guessing. Our VIN lookup resolves the near-identical alternators numbers for you.
• Ships from Dallas. Alternators ordered by 3pm Central go out the same business day.
• Straightforward returns. No restocking games on alternators that did not fit.

Ordering correctly

Aftermarket versions are often close enough to install and far enough off to cause a repeat repair. Option packages divide this catalog more than model years do. Send the VIN and skip the problem. Our Dallas location means most of the country is inside a two or three day ground window.
