I have a 2in body lift and the 3.5 sl with long arms, The bronco has more body roll on the street but off road it works great, I have 35s and they rub the front shocks when i turn all the way left or right but no big deal.. I put a 37 on to see if i would rub and i would alittle on the front inner fender where it meets the outer at front but nothing i cannot fix, ,also the rear with a 37 would rub just a touch at the back inner fender, again nothing that i cant fix with a little bending.. with 2in bl and 5.5 sl you will only have rubbing on the shocks in front when turned all the way but nothing major. Then again you half to account for your rims and the offset they have.. O and i have 2 shocks per corner and the ride is great.
