About this kit

3.5-Inch Lift Kit with M1 Loaded Struts, fitment-checked

11440 is the M1 configuration: forged aluminum upper control arms paired with an M1 loaded strut pair rated for 3.5in of front lift, covering 2021–2026 Tahoe, Suburban, Yukon and Yukon XL 4WD. POM ball joints arrive pre-installed. Minor trimming is required, wheels must be 20in or larger, and magneride or Adaptive Air Ride trucks will not work.

This 3.5-inch lift kit for 2021–2026 Tahoe, Suburban, Yukon, and Yukon XL 4WD is the M1 build, matching forged aluminum upper control arms to an M1 loaded strut pair sized at 3.5in. The arms come with POM ball joints already installed, which keeps the bench work short, and stock geometry is reset for the new ride height rather than stretched. Plan for minor trimming, 20in or larger wheels, and removal of the front differential mass damper if your truck has one. AT4, Premier, High Country, magneride, and Adaptive Air Ride are excluded. A downloadable installation guide is available.
