I have asked this question a FEW times. I have a 2" OME lift and am tryin to fit 31's. I was looking into the Teraflex Budget boost from 4wd.com. I need to know if I need 2 BPE's or 4? Also will the budget boost get me to 4 inches because I only want 3" to 3.5"?

 

You need two sets of two which = 4 total.

But call the supplier just to make sure.



As for the hight you will probably get just over 3.5".
