2013 Chevrolet Suburban 2500 Alternators

Genuine GM alternators for the 2013 Chevrolet Suburban 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 Suburban with the heavier frame and the 6.0L V8.

When to replace

A battery light, dimming headlights at idle, or a no-start after a short drive. On a full-size SUV, wheelbase and drivetrain separate vehicles that look identical in the parking lot.

Why order factory

• VIN verified fitment. We confirm the alternators number against your vehicle before it ships.
• Same day dispatch. Order alternators by mid-afternoon and it leaves our warehouse that day.
• Returns without a fight. We would rather fix a alternators order than argue about it.
• Covered by GM. On alternators that coverage is worth more than the price gap.
• Real wholesale. The same alternators your dealer sells, at a fraction over our cost.

Avoiding the wrong part

The factory number ties back to GM engineering records, which is something no aftermarket catalog can offer. Give us the number stamped on the old part and we will trace what it superseded to. Same day shipping on in stock items, direct from one of the largest GM parts warehouses in the country.
