It's that time. Everyone's suggesting 4.10 and 4.56 gears.
I'm wanting a good daily driver with best mileage, full time OD, seldom off-road
2020 JLU
3.6 manual 6spd
DANA M186 front axle
DANA M220 rear axle
3.45 overall gear ratio
35" tires
(I'm averaging 16.1 combined mileage now with 35")
Looks to me like the 4.10 is closest to my needs. The 4.56 gears are more performance minded for 35"
Any thoughts before I pull the trigger on re-gearing. I only want to do this once.
I want to get this as close to as it was stock regarding rpm's, power, overdrive.

According to the calculator, I need as close to 4.18 to return stock performance. So 4.10 may be slightly sluggish, but 4.56 runs the rpms higher. I live in flat A$$ Florida, not doing any crawling. Occasional mild trails, 98% daily driver.
I know the 4.56 will get more "pep". I want to restore 6th back close to stock as I'm on the interstate 50% of the time and od will help with mileage.
