Have the straight 6 in my XJ with stock gears I think they are 3.55 ratio and my buddy had bought some 4:10 and decided to go with 4.55 so he hooked me up with the 4:10'a pretty cheap. I run a 33x12.50 15 tire how much will the 4:10's help and will it help on my gas mileage or make it worse?

Not my DD I have a new truck but I usually drive the XJ around town sometimes. Just when I'm not going very far but I wheel it lightly usually not to hard. The front axle is locked so I do what I can with it

4:10's will be an improvement over 3:55, what tranny do you have? Standard or auto? If its more of a wheeler then any thing else I would look into getting
4:56-4:88's. Also what rear end do you have? You might want to look into getting a new one if you have a Dana 35 BEFORE you go for a gear change.
