Hello all. I'm looking at re-gearing my JK. I have an auto trans and currently have 3.21 w my 33" tires. It's not too bad but looking to up my towing capabilities. I've done the mat and was curious if anyone can confirm that with 4.11 gears and 33" tires I would be running between 2400-2500 RPM @ 70 mph? Thanks...
