About this kit
3.5-Inch Lift Kit with Forged Upper Control Arms, fitment-checked
Rough Country 11400 delivers 3.5 inches of lift on 2021–2025 Tahoe, Suburban, Yukon and Yukon XL 4WD using forged aluminum upper control arms with POM ball joints already pressed in. Minor trimming is part of the install, wheels must be 20in or larger, and any mass damper on the front differential has to come off. Magnetic Ride Control and Adaptive Air Ride trucks are excluded.
This 3.5-inch lift kit for the 2021–2025 Chevrolet Tahoe and Suburban, GMC Yukon and Yukon XL in 4WD is centered on forged aluminum upper control arms cut with laser precision and shipped with the ball joints already installed. The POM joints give the arm a wider range of motion and cut down the bench work. Plan on minor trimming during installation, 20in or larger wheels, and removal of the front differential mass damper if your truck has one. AT4, Premier, High Country, and any vehicle with Magnetic Ride Control or Adaptive Air Ride are excluded. A downloadable installation guide is available.
