2011 GMC Sierra 2500 HD Serpentine Belts

Genuine GM serpentine belts for the 2011 GMC Sierra 2500 HD, at wholesale prices. Belt length is determined by the accessory layout, which changes with AC, alternator rating and tow package. GMT900 HD through 2014, K2XX HD from 2015 to 2019, and the T1XX HD from 2020.

Symptoms to look for

Squeal on cold start, visible cracking, or a belt that keeps throwing. On a heavy duty pickup, single or dual rear wheels, gas or diesel, and cab configuration divide this group more than the model year does.

Why order factory

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

Ordering correctly

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 Give us the number stamped on the old part and we will trace what it superseded to.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.
