GM 9L7 Upfitter Switch Package

Upgrade your 2024–2026 GMC Sierra HD with the Genuine GM 9L7 Upfitter Package — the same factory auxiliary switch kit available on high-end AT4, AT4X, Denali HD, and Denali Ultimate trims. This kit gives you clean OE integration and ready-to-use 12V switch outputs, all with zero dealer programming required.

Everything is Genuine GM, designed for a straightforward, bolt-in install. Perfect for powering LED lights, air compressors, or any work accessories — all controlled directly from your factory console.

Features:

✔ Genuine GM Parts – Factory quality, durability, and exact fit
✔ 5-Bank Auxiliary Switches – Power up to five accessories
✔ OEM Console Panel & Fuse Block – Clean, factory-style integration
✔ Complete Hardware Kit – Includes all wiring, fasteners, and fuses
✔ Free Installation Guide – Included for professional installation assistance
✔ FREE Shipping Options

📌 Install Tip:
GM’s factory fuse block is designed to zip-tie to the HVAC assembly (not the neatest). For a cleaner install, add our Upfitter Switch Extension — it allows you to install without leaving the connector and wire pulling SUPER tight at the switch.
👉 Just use the Frequently Bought Together option above to grab both with one click.
