Installation Notes and Tips

Verify the vehicle is a right-side application and confirm the truck is listed without body cladding before ordering. Compare the existing panel to part number GM1221131 and OEM reference 15798922 to confirm the mounting points and overall shape match your vehicle.

Professional body repair installation is recommended because proper alignment affects headlamp positioning and front-end fitment. Test-fit the panel before final attachment to ensure the headlight housing support sits correctly on the Chevrolet Silverado or Avalanche platform.
