I was wondering. My 99 XJ has the 3.55 gears. What would I half to do to swap in some 3.73 {if I could find some}? I use my XJ alot to pull fourwheelers and think the gear change would help alot. I think the 3.55 is just too high geared.

 

Its not easy or cheap to do gears, you probably aren't even going to notice that much of a difference, i'd go to a little lower than that if you really want to see a difference, like 4.10's. Depends on what size tires you have though.

 

I see, It does seem expensive to regear but I could prolly do it pretty cheap from the Junk Yard. 4.10 gears would be in a 4cyl model Jeep right? I have 245/75/16" tires.
