Thanks,

It's going hard to find that since the auto XJs came with the 3.55 ratio and the manuals, have 3.07 gears. I have heard 3.73 was a rare option but I have never seen it on an XJ.

 

Yeah I know,, I have heard a "few" of the towing package optioned ones had 3.73's
12 months into this build with my son, so I don't want to cheap out and go next best option.
5spd with 31 tires,, we have a set of 3.55 axles, and they would "work" , but we will be towing a small trailer once in a blue moon., 4.10 would be too steep for the highway travel.
Using the original 3.07 gears and 28" tires as a base. going to a 31" tire would be a 10% increase in diameter , going from 3.07 to 3.55 would be a 15% increase, but realy want that little extra 3.73's would give me (21% increase).
