Not even to future proof bigger tires? So 4.56's then? And I was looking at that rawk hoss supply or whatever it's called on the forum. But I wasn't able to call cuz I was pretty busy.
On a side note, Looks like me and the girlfriend are going to head to bunce school road Friday morning to do a little wheeling and play in the snow to do a shake down run, anyone want to join us?

Bigger then 35's on a 8.25 and D30? Not a good idea my friend. Go 4.56. I had 35's and 4.56 and it was perfect for the road and perfect for highway. 4.88 you start getting into really small pinion's and that can be a problem. My buddy has trashed a 4.88 D30 and 8.25 pinion gear wheeling. There just to small for bigger tires. He also has a 4 to 1 but still. Go 4.56 man. Listen to the people here and dont be dumb.

cost of gears +labor on 2 axles and you will probably sell the XJ before you make your money back in fuel savings , But I'd try and sell the oldman on needing the correct gearing to make the transmission happy .

Was planning on keeping it for the rest of my life anyway. Plus 5 or 6 mpg ain't treating my wallet too well.

I would be truly interested to know your before and after mpg from this gear swap. Be sure to keep good records. He i thought my Highboy's 10mpg was pretty dismal.

Yeah I'll try to get some decent numbers before I do it. What's the best why to go about this though?
