I am going to put a super lift on my 06' fx4 level ll soon with the 6" skyjacker leaf prings. Since I bought the lift parts used I have no shocks. I can get the superlift shocks but I was wondering if I could put others on, I'm hoping bilstein 5100s. Do they or anyone else make a shock that will work, and has anyone done this? The super lift shocks are 30.07" extended and 17.70" collapsed.
