2012 GMC Sierra 2500 HD Window Regulators

Genuine GM window regulators for the 2012 GMC Sierra 2500 HD, at wholesale prices. Regulators are handed and differ between front and rear doors and between express and standard windows. GMT900 HD through 2014, K2XX HD from 2015 to 2019, and the T1XX HD from 2020.

Symptoms to look for

A window that drops into the door or moves slowly and unevenly. On a heavy duty pickup, box length and cab style drive more part number splits here than the engine does.

What sets these apart

• No hassle returns. If the window regulators is not right, send it back.
• Warranty intact. OEM window regulators keep coverage that an aftermarket part can void.
• Wholesale pricing. Most window regulators numbers land well below dealer list.
• No aftermarket substitutes. These are GM window regulators, not OE-style equivalents.

Ordering correctly

A part validated on this vehicle behaves differently from one validated across a range of vehicles. Fitment questions are the one thing worth a phone call before checkout rather than after delivery. We ship from Dallas, which keeps transit times short across most of the country.
