Before doing this though, you can try flexing your rig, if the shackles dont move like they are supposed to, theyre probably overly tightened.

For clarification, did you ditch the trac bar in front or just the sway bars? The first thing I did was toss the front and rear trac bars into the scrap pile.

finally, as others have stated, the spring brand makes a huge difference. Procomp and Rough Country are two companies known for really stiff YJ springs. I know cuz I have 2.5inch procomps. I finally got her to flex good, but the ride is not nearly as sweet as a set of OME springs. Your profile as others stated says youve got BDS springs. Are you sure theyre BDS?
I hate to disagree with you but by torquing your shackle bolts to 35-40 pounds what you have done is let the shackles move on the bolt.
What this will do is either wear the bolt out or oblong the holes in the shackle.
As Anti picture shows the sleave in the bushing is the thing that should move.
That is why there are greasable shackles.
Pull the sleaves out and grease those, then torque to factory spec.

Never had any signs of wear on my bolts or shackles being torqued to 40ftlbs for 8 years. On my 95

I have the black diamond lift on my 95 and yes it rides rough, especially with the shocks it came with. Hopefully going to bilsteins in the future would help.

What tire pressure are you running?

That makes a huge difference in my Jeep. I run 28psi in my 32s.

Based upon what I've read, I'd make sure your shocks are not maxed out and acting as the stops for the suspension travel. I just found that issue on my co-worker's Cherokee after he did a lift. the rears had no downward travel due to improper shock length and made his veh ride horribly over even the smallest bump.
