I just installed a set of 919 springs today. I had done a lot of reading on the different spring options before I decided on the 919's. From what I had seen different people say, I thought I would get about 1.75-2" of lift. Well they gave me exactly 3"s! I measured from the floor to the top of the wheel arch with stock springs, 40" & exactly 43" afterwards. I have a feeling once the truck is all back together & I drive it some that it will come down a little bit. But I just thought I'd post my findings.
