2014 GMC Sierra 2500 HD Serpentine Belts

Genuine GM serpentine belts for the 2014 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.

When you need them

Squeal on cold start, visible cracking, or a belt that keeps throwing. On a heavy duty pickup, cab configuration, drivetrain and box length all split this group, so the badge on the tailgate is not enough to order from.

Buying OEM, briefly

• GM stands behind it. The serpentine belts warranty comes from the manufacturer, not from us.
• Priced below the dealer. Serpentine Belts at up to 40 percent off list, with no membership.
• Factory sourced. These serpentine belts are built to GM's own drawing by the supplier GM contracted.
• No guessing. Our VIN lookup resolves the near-identical serpentine belts numbers for you.
• Ships from Dallas. Serpentine Belts ordered by 3pm Central go out the same business day.

Getting the right part

Original tooling means original fit, which matters most on anything that has to align with a neighboring part. Our VIN lookup is more accurate than any public catalog. Use it before you check out. In stock orders placed by 3pm Central ship the same business day from our Dallas warehouse.
