Now we're getting somewhere. The good news is you have a decent rear end with the 3.73. I have the same set up on my 2014 Sahara and I have a 2.5" lift with 35x12.5x18 wheels & tires. My JK sits on a little rake due to the 80lb front bumper and the true lift sits right at 2". This is a pretty good look at the profile before I installed the heavier front bumper.

Some people may suggest a gear upgrade to a 4.10 or a 4.56. That's okay and I can't speak to that because I'm okay with the 3.73. That may change in the near future if I start towing a trailer, but right now, with a Pedal Commander installed, I do some mild trails and can still run comfortably at 80 on the interstate.
The other thing to keep in mind is the geometry changes in your suspension when you go more than 2.5". You'll need adjustable control arms, drag link, etc., whereas with a 2 - 2.5" you don't necessarily need to replace/upgrade everything. I've upgraded when I needed to replace the shocks and replace the drag link, but everything else remains fairly stock.
