2006 2wd I m 2.5 in lower in front than rear that was what I was hoping for thanksdepends on what year you are and if your 2wd or 4wd. 2" is ok on pre 08 2wd and 4wd. If you are an 08+ 4wd you will need to replace the upper control arms or you will have issues, mainly Coil Bucket contact which will eventually lead to a failed Upper Control arm
