I know this question has been posted many times, have read many post on many forums, but I am hoping for some real world jeepers running 3.21 on 35's.
My 2015 JKU with automatic that currently has a 2.5" TF coil lift and is running stock wheels/tires. Next mods will be new control arms and trackbars, then wheels and tires or regear?
I have seen all the graphs/charts and understand most of the math with running 35's on 3.21, would probably switch to 4.56 of 4.88, but I am looking for real world users. Re-gearing has always been on my list, but its always been after 35's. And yes I would be using a recalibrator to adjust for tire size.
I drive ~70 miles a day on my jeep during the work week, mostly highway at 60-75 mph, I put a ton of miles on my jeep, 24k in the first year.
So to those real world jeepers on 3.21 with 35's and those who have actually run it...
How does it perform?
Does 5th gear exist?
What RPM's are you at when you hit 60-75mph on the highway?
Do you regret not re-gearing first?
Whats your mpg with 3.21 on 35's?
Other thoughts?
Thanks in advanced.
