Hello, I only did the Rough Country 2 inch in the front and my 275/65R20 KO2 fit perfect no rubbing giving an extra inch of hieght. it raised 3 inches total in the front and 1 inch in the back. No lights on dash, no issues checked with dealership no warranties will be affected. Cost Country Rough Kit installed aligned and balanced $255.72 and $1,040.00 on tires Total $1,295.72. It's 1 inch lower than the AT4 on the back and same level as AT4 on the front it looks and drives great.
