6-Inch Lift Kit with M1 Struts, fitment-checked
Choose Rough Country 11140 when the 6-inch Tahoe or Yukon build calls for M1 struts: the kit ships an M1 loaded strut pair alongside the crossmembers, cast knuckles and full front skid plate. Coverage runs 2021-2024 Tahoe and Yukon 4WD plus 2021-2024 Yukon XL, gas engines only, on 20-inch or larger wheels.
The M1 strut option for the 6-inch Tahoe and Yukon lift, covering gas 4WD models from 2021-2024 plus Yukon XL through 2021-2024. Struts come loaded and ready to bolt in, which keeps strut disassembly and a spring compressor out of the driveway. Also boxed: front and rear crossmembers, driver and passenger cast knuckles, and a full front skid plate. Before ordering, rule out Magnetic Ride Control, standard on AT4, Premier, and High Country and optional on RST and Z71, and rule out Adaptive Air Ride. Wheels must be 20 inches or larger. A downloadable installation guide is available.
