Great first post dude. You are on the right track to be an official fuck. At least you have kept up with the mysterious rule of "DAN Tuesday".
As for your issue...The lift you bought is notoriously stiff. The only off-roading improvement you will see is the ability to fit those LTB's you bought.
You would have been better off cutting the fenders, adding bumpstops for the up travel, and putting a little bit of body lift under it.
While I kind of agree here.....
Make sure the shackle bolts aren't too tight (common mistake).
Open up the spring clamps a little bit.
Wheel the every living crap out of it. Seriously. Find a crappy section of road/trail and hammer it. Get the springs to break in. Couple trips like that and you should see some improvements.
Course your first hint should have been in the name "Rough Country"... did you expect them to be soft
Scout lift spring technology from most manufactures hasn't change in the last 30 years, so don't expect TJ ride. Thick, stiff leaves are still the norm. If your lucky they won't prematurely sag from the (likely) crappy manufacturing method.
Nothing wrong with 4" lift springs in principle, just don't expect smooth ride and awesome articulation.
