I am deciding on whether to get a complete package 2" lift kit or an Add-A-Leaf kit but was wondering if I would need an SYE as well because it would at 250 to the overall cost...

A 2" suspension lift typically will not give you any problems with the driveline. It starts being a real issue at about 4" of lift. If you get any vibration at all, you can shim your skid plate down with washers, thus decreasing the angle of the driveline. You should not have to do that with only a 2" susp. lift.

Hey, as long as we are sort of on the subject, I've heard people talking about re-arcing springs. Is this a real thing? I don't really know, but mine are getting flat after 13 years of on-road off-road. I've pretty much decided after all these years to probably just go with a very mild 2" spring lift, but it has gotten me to wondering about these dang flattening springs....

a lot of people run 4" lifts with no sye and just a transfer case lowering kit...you shouldn't get any vibrations and if so they will be very mild and just a transfer case drop with spacers would fix it...a lot of 2" Budget boosts (although you have leafs) don't even come with transfer case drop kits...and the pro comp 2" coil lift doesn't come with a transfer case drop kit

That does seem like a persistent problem with leaf springs. We have a member of our Jeep club that has been through 3 sets of leaf springs, due to loosing their arch. I have also heard of having them re-arched, but would think they would eventually settle again. Old Man Emu, says they guarantee their springs won't sag, but I have no experience with their product. I can only tell you that the Rough Country leaf springs don't seem to last very long. I would think that one could place a add-a-leaf into the mix, and possibly regain some support.

I haven't decided what to do about it yet. The add a leaf seems the way to go to help curve sagging.

Make sure you torque the spring U bolts correctly.
My lift was already done when I bought the Jeep. After investing in a slip joint elemenator and two drive shafts. I found that the spring U bolts were loose and causing the axel to shift.
