Great
Upgrade your 2024–2025 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

✔ 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

📌 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. If you do not purchase this, we cannot help you if your switches pop through the bottom which we have noticed with a few that did NOT purchase and left them super tight.
👉 Just use the Frequently Bought Together option above to grab both with one click.
