My jeep grand cherokee zj 96 limited needs a change of rear gear ring and pinion set, and I want to know what is a better gear ratio to use. I use the jeep 80% on pavement and 20 percent off-road (gravelly and muddy) sometimes with towing load.

You are supposed to have stronger torque with a higher ratio, so 3:73 should theoretically give you more pulling power, but practically speaking the difference can barely be felt.
Word of advice, if you are not changing tire diameter size significantly and your front differential is still okay, don't use a ratio different from your front.

Leave it as-is. The difference is minimal, unless you are going to put on tires larger than 31". Then you will need lower gears, like 4.10:1-4.56:1. If your jeep is a 4.0L, it's only got around 200 horsepower at very best, being a 96 its probably down to 150. Changing your gearing (yes, you have to do both front and rear) is either going to be (a) kind of expensive and a lot of trouble, or (b) very expensive to have somebody else to do. If you don't do major off-roading, and aren't towing a Bay liner, then just let it be. If you need a lot more power, sell it and get a 3/4 ton vehicle. That will be less trouble and more cost effective in the long run.

IF its four wheel drive . match the ratio of the front set .. just in case you ever have to use your four wheel drive on pavement .. the reason for this is .. is that you have a chain driven transfer case and if you run an unmatched gear set in them .. chances are great that you will do damage .. other factors to consider are the fact that your speedometer is going to be off .. if you go with a lower or higher gear set and between a 3:55 and a 3:73 .. theres not that much change .. but enough to be a head ache .. the gain is minimal and the problems that could occur are many ..

Depends if you want to change both sets of gears. I would personally go with 3:73's but it depends on what you're front diff has. You will either have to match those or, change both.

3:73 if you two frequently or heavily....3:55 for better gas milage
since you off road and tow I'd go 3:73

often times the service or the housing can in common words take particular contraptions of gears. in case you analyze the area numbers you may be in a position to inform earlier you purchase. some equipment vendors can help you with that, attempt Richmond equipment. provide a decision and tell them what you've...

you cant change one with out doing the other... or your gonna end up in deep stuff .. just stick back what you had in there chances are you had the 3:55 and its not that bad of a gear

If it's 4x4 then you will need to stay with the current ratio so you don't tear-up the transfer case. If you do decide to change the ratio then you will have to change the front as well.
