About this kit
6-Inch Lift Kit with M1 Struts, fitment-checked
The M1 build of the 6-inch kit for the 2021-2024 Chevy Suburban and GMC Yukon XL 4WD, shipping with an M1 loaded strut pair so the front struts go on assembled. Cast knuckles, front and rear crossmembers, and a full front skid plate are included. Not for Magnetic Ride Control or Adaptive Air Ride trucks; 20-inch or larger wheels required.
Same 6-inch lift, different damping: this version of the Suburban and Yukon XL kit ships with the M1 loaded strut pair, and the assembled struts keep a strut compressor out of the job. The rest of the boxes carry front and rear crossmembers, driver and passenger cast knuckles, and a full front skid plate. Trucks with Magnetic Ride Control — standard on AT4, Premier, and High Country — or with Adaptive Air Ride do not fit, wheels need to be 20 inches or larger, and a mass damper on the front differential has to come off. Cutting and drilling required.
