Setup: 2010 Unlimited Rubicon Manual on its way to AEV for 4.5" lift with 37" tires, 5.13 gears, front and rear bumper.

Question: I am on the fence about Hemi - from members who have had a stock with 37" tires and 5.13 gears to the Hemi upgrade - do I need the Hemi? Is the ride that much different? I realize it is a luxury item, just how badly will I want the Hemi with the 37" tires?

I understand its a jeep and I'm not looking for a fast sports car (I have a Ford F250 for towing), I just want to make sure the jeep is still a fun rig to drive.

Thanks in advance for the advise and your experiences,
