I use this vehicle daily!
Sometimes I'm in to mud up to my ass
I tow items weighing up to 2500lbs.
Any other info needed, feel free to ask.

well rubicon express sells there 3.5 inch kit and it is as close to a stock ride as you are going to get.

I have heard that OME makes their kits tuned for various applications such as towing or softer ride, etc. You might look into that.

I second the RE kit. I love my RE springs, they ride very good (although I very rarely take it on the highway)...
