Genuine GM switches for the 2011 GMC Sierra 2500 HD, at wholesale prices. Switch part numbers split on trim, door position and whether the vehicle has express up and down. GMT900 HD through 2014, K2XX HD from 2015 to 2019, and the T1XX HD from 2020.

How you know

A window that only works from one door, or a switch that sticks. 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

• Factory warranty. Genuine switches carry GM coverage aftermarket cannot match.
• Dealer parts, not dealer prices. Compare our switches pricing against a counter quote.
• Genuine GM only. Every switches listing carries the original factory part number.
• Fitment checked by a person. Send the VIN and we verify the switches before the box leaves.
• Central shipping origin. Dallas keeps switches transit times short nationwide.

Confirming fitment

Factory parts are built to the tolerances the vehicle was engineered around, not copied from a worn sample. A photo is rarely enough to order from. The VIN takes seconds and removes the guesswork. Freight is quoted at what it actually costs, not inflated to subsidize a headline discount.
