From what I have read, most people who install V code springs, gain around 1.5” of lift in the front. My questions is, what is the amount of lift people have experienced in the rear after installing: unmodified B code springs? B code + one leaf? B code + two leaves? unmodified F code? F code + one leaf? For those who reply, please indicated what size block was used along with the spring installation. If RAS was also part of the set up, please note that as well. My desire is to install the V code springs on the front of my 2001 7.3l diesel Excursion, and do what is required to end up with the rear sitting 1.5”, or so , above the front. Thank you.
