Like others have stated, 4+ requires long arm with large tires. If you kept your tires to 33s, then it's not as much required unless you actually push yourself in wheeling.
What happens is the arms get steep angles. With the front axle higher than the rear, then the rear axle will tend to walk under the Jeep and lift the front.
If you are near KC, I can show you that I can lift my left front tire with the 4cyl/auto I've got. I'm running 2" bb and Rubi coils, Currie rear adj upper arms, Tera front adj lower arms, RE front track, rear track riser in the rear. Pretty simple to do and I'm only running 34's....
To me, biggest PITA would be the 35x12.5s breaking the rear axles....
