I think regearing from 3.73's to 4.10's is a complete waste of time and money, I doubt you will even notice the difference.
If you have the manual tranny (or swapped in auto with overdrive) I suggest regearing as low as you can go, 4.88's or deeper.
My old Rubicon was an absolute slug with the stock 4.10's and 31's.
Now before people even suggest a drop in gas mileage, the absolute best mileage I ever got (21-22 mpg)with the Jeep was with 35's and 5.13's.
Just my opinion.
