I finally pulled the trigger on some Bilstein 5100s and got them installed Saturday. Huge difference. The Jeep feels alot more firm now, but rides much smoother on rough roads. I also figured out the sagging problem. Once I actually pulled off a tire and climbed underneath it was pretty obvious, my coil had slid off the 1" coil spacer and crushed it. So I ordered new 1.75" Daystar spacers and I'll install the Air Lift 1000 kit at the same time. I'll report back when I get the air bags installed but I expect them to make the Jeep work much better when it's loaded down.
