I am sorry that I still yet have to install my leveling kit so I can't answer that from experience but I did my research as to the actual lift you get with specific kits, not the advertiser's increase. Also are you running stock rims and tire widths, that matters, but the biggest thing I've found over 40 years is that all tire diameters are not the same as they pretend to be. I've had Super Swampers that said 36" come in it at 36-7/8s. and thats with recommended tire pressure and this was true for four different sets.
BF Goodrich All terrains run 1/2 to 7/8ths less than advertised. Actually all the all terrains I've run, no matter the manufacturer, are always almost an inch less than advertised. Radial Mud tires are generally right on the money, but Bias Ply tires seem to run big. Also remember you have to measure them off the vehicle, with no load on them.
Good Luck if you haven't done it yet.
