About 2019+ GMC Sierra 1500 (T1XX)

The T1XX-generation GMC Sierra 1500, introduced for 2019, brought a stiffer frame, updated suspension geometry, and a wider range of trims — giving aftermarket builders a solid foundation to work from. Whether you run a Trail Boss, AT4, or a base model you've built up yourself, the right parts can transform how your Sierra handles on the trail and on the street.

What to Look for When Upgrading Your Sierra 1500

  • Suspension: Confirm lift or leveling kits are rated for your specific cab and bed configuration, and check compatibility with factory features like MagneRide if equipped.
  • Bumpers and armor: Look for parts designed around the T1XX's front-end sensors and camera locations to avoid losing driver-assist functionality.
  • Wheels and tires: The T1XX uses a 6x139.7 bolt pattern — verify offset and backspacing before ordering to avoid rubbing issues.
  • Lighting: LED light bars and pod lights should be matched to your grille or bumper setup for a clean, functional install.
