Honestly I don't know. Maybe 1.5-2". I didn't measure when I put them on. The coils I used are MOOG P/N CC810.
According to the MOOG catalog:
Free height of 17"s (all the RBV's are 13"s).
Installed height of 13" (RBV's 10").
Load Rate of 1100 lbs (RBV's 899-1650 lbs).
Spring Rate of 270 lbs (RBV's 357-489 lbs).
The lighter Spring Rate is why I'm guessing 1.5-2"s. They are very soft springs!! I'm not running a sway bar but I am running dual JD front shocks. I drive the piss out of it BUT I also understand that it handles differently than a stock truck.
If you have ever witnessed a baja truck take off and the front end goes skyward....well that is what my truck does. It's not quite that bad but it is noticable. I would like to try an adapt the Currie Anti-Rock to the BII. I believe that would help alot.
Sorry it has taken so long for me to answer. I work 2 jobs so free time doesn't show up often. If you have other questions you can text me at 405-615-7110 or e-mail at
