Genuine GM serpentine belts for the 2013 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.

What sends people here

Squeal on cold start, visible cracking, or a belt that keeps throwing. On a heavy duty pickup, box length and cab style drive more part number splits here than the engine does.

The case for genuine GM

• Ships from Dallas. Serpentine Belts ordered by 3pm Central go out the same business day.
• Straightforward returns. No restocking games on serpentine belts that did not fit.
• GM stands behind it. The serpentine belts warranty comes from the manufacturer, not from us.

Before you order

When a component is superseded, GM documents why. That history is worth having when something failed early. Two vehicles off the same line in the same week can take different parts. The VIN is how we tell. Most orders leave the same day. Oversized and freight items take an extra day to crate.
