I purchased the Pro Comp Nitro lift from Amazon (part 61180K) for $265. And had it installed. The lift description says 2.5" front and 1" rear.
My stock measurements were 37" front (from ground to wheel well) and 39" rear. After the installation measurements were 40" front and 41" rear. So 3" front and 2" rear gain.
I am planning on keeping the factory wheels on, as I like the look of them. The wheels are 20 x 8. So I will have to run the 295/65r20 tire. Im fairly certain these will fit as they are only 11.6" wide. The local tire shop says no way they will fit so I am prepared to use a 1" wheel spacer if needed, but I think they are wrong.
I am very pleased with the look of the level kit. Now I just have to convince the wife I need to spend $1600 on tires.
