How much lift on my X to fit 37x12.5x17 tires?

Just need some help here. Want to lift my excursion and keep getting alot of different answers. How much lift do I need to fit 37's? Some manufacturers say 8" and others say it will work with 6". Any help would be appreciated. Thanks.

I would do the 8" lift.
I have 37x13.50 tires w/ 20x10 wheels and -43 offset....and and times my tire hits the inner front fenderwell.
I'm looking into adding 2 more inches to the existing lift.

Superlift tech are telling me no rubbing on a 37" x12.5 tire if I run their 7" suspension kit Going to play it safe and run a BFG KM2 345/75/16 (36.4")with a 4.5 backspacing on a 9" wheel. Superlift also says no driveshaft mods? Anyone else running this lift and having driveshaft issues?

Thanks for all of the info.

Good luck I wouldn't try it..most lift companys don't understand the Ex and just sell you a truck lift..not going to cut it.

If I could do it again I would have done the 10" lift BDS sells w/ the same tires and wheels.
Keep us posted and take some pics.

I don't think you could lift it that high and not modify the rear drive shaft. At 6 1/2 inches I occasionally get rear driveline vibrations.

If you get the glassworks fenders you can do it with about 3" of lift. Guy by the name of JDHolder had a Ex with 5" of lift, the fenders, and 40" tires stuffed under it. The fenders are about $400 right now.
