This lift kit is for 2001 - 2010 Chevy or GMC 1 - ton and 3/4 - ton 4WD trucks, especially diesel models. To use it, first, you'll need a Torsion Bar Tool to load and unload the torsion bars. Some welding work and modifications to the frame bracket and differential mount are required during installation. Also, traction bars won't fit standard cab/short box models and are only for vehicles with a 4 - 8' lift. For tire and wheel combinations, you can choose from the options provided. To reduce trimming, it's recommended to use 20' wheels with 5 - 5.75' backspacing. If you want a tail - high stance, use the recommended add - a - leaf parts. Maintenance is important. Regularly check the brackets, shocks, and other components for any signs of wear or damage. After driving on rough terrains, clean the kit to prevent dirt and debris from causing problems. And don't forget, this kit isn't suitable for Suburban/Yukon models with AutoTrac Transfer Case or rear Autoride - equipped SUVs.
