It is a guessing game, it's not hard just time consuming, IMHO a proper set up bastard pack usually will out flex a new lift pack, and usually rides better. Springs have allready sagged and they are broken in. Well worth a Saturday of your time, pick up a case and invite a friend over.

I would think that you could just bolt everything up loosely and put the weight on it to test the height. Then tighten it down once you get what you want?
Also where could I check to make sure things are level?

I would just use a make shift plumb-bob, I use them also when centering axles for spring perch set ups.

I'm in the same boat with sagging rear springs.
What's the difference between the standard and HD OEM springs you can get from Quadratec? Are the HD ones stiffer? Harsher ride?

Ah gotcha, that makes things easy.
Do you really wanna spend that kind of money for stock ride height? Think Im gonna go with used springs for like $100 to hold out of lift springs for a year or two.

Plus, correct me if I'm wrong, with new springs, don't they take a little time to settle into a lower ride height after install?

Settling takes a few days, and its not much of a change. If you dont want to lift it then by all means go with a factory replacement, nothin wrong with that.
in a similar boat but looking for lift. new leafs are one of the more expensive replacements so i'm all for bastard packs. JY's are good but check CL, you save time since they're already pulled
i picked up a pair of wagoneer springs for $20. going to try and put it together this weekend; looks promising as the 2nd spring is same length as top xj spring, and they came with an overload spring. i'll keep you posted.

all in all, for $25 the donor leaf packs worked really well. netted around 2" inches over the beat stock springs and got an overload leaf.
so now i'm running 31's with ~3.5" lift and some fender trimming. only problem is now i have driveline vibrations. sye time i guess.
