I cannot help you with stock measurements, however the Rocky Road lift and stock tires put the center on my wheel wells at 34 1/4" in the front and 35" in the rear.

This measurement is from the ground to the lower edge of the fender flair, centered on the tire.

I think he wants to know the measurement from the from the ground to the lowest point underneath the vehicle, which is what ground clearance is.

According to the Jeep website the stock ground clearance is 8.6 inches. The lowest point is the rear axle.

A lift will not help you with lowest ground clearnce, becuase the lowest point is the rear diff. Lifts help with all other areas of clearance. Now if you want to rise your lowest point, you will need bigger tires. That is what I have always been told.

Exactly. That's what I was going to say, but you beat me to it.

However, keep in mind that a lift will give you extra clearance under the vehicle in spots other than the rear axle & differential and some of the front suspension components, like the lower A-arms, for example.

Also keep in mind that the only way to get those bigger tires in your wheel well is to add a lift. You really can't have one without the other. Also the main areas that ground clearance matters is 1.approach angle 2.breakover angle 3.and departure angle. 2-3 inches makes a big difference in those spots. If you follow a good line your diff shouldn't be on the high spots, your tires should hit the high spots.

Good point. I don't have actual measurments, but this picture shows a reasonable difference between my wife's '08 and my '06 which in this picture still has the 2.25"RR lift and 265/70's. I'm still running these tires so my ground clearance has not increased. In fact, after I added the 4" lift, I installed the RR supersliders, negating any rocker clearance advantage I had just gained. But I've been on them enough to know they're worth the money.

great picture, it really shows a great difference. Keep in mind that if anyone is running a 2.25 RR lift and 265/75's your actual increase in height is 3.25" lift and tires included.
