Given this vehicle has OD axle ratios are not as scarey. A 4.10 would
be a big improvement and might be want you want based on your driving.
A 4.56 would play better here if you live in a hilly area or at a
higher elevation too. One more note, 3.73 with 33's is about the same
in effective gear ratio as stock 225's and 3.07 gears which is no barn
burner either. So you really do not want to go 3.73 route unless you
plan to go to smaller tires than 33's.

4.56 is as close as it gets to how it was stock.

Re: REGEARING FROM 3.07 TO EITHER 3.73 OR 4.11
 

Sorry, but that is incorrect. Her original gear ratio is 3.07 and her
tires were 29". It's s simple ratio between the tire diameter and gear
ratio to maintain the same RPM. 29/3.07=9.45. If she maintains that same
ratio between tire diameter and gear ratio, her RPM will remain the
same. To calculate the gear ratio, she just needs to divide the tire
diameter by 9.45 to get the proper gear ratio if she wants to achieve
the same RPM as original.

for 31s it would be 3.26
for 33s it would be 3.49
