It seems like most people are liking 4.88s with 35s. That's what I plan to get at some point.
With an automatic 4 dr Rubi & 35s, you want 5.38 gears. They will put you at about 2500 rpm at 70 mph--which is about the same as a stock 6 speed Rubi on stock Rubi tires.Sorry to revive a really old thread. I ended up going w/34s and stock 4.10 gears which works OK, but as my 34s wear down I have recently been thinking of upgrading to 35s and 4.56 or 4.88 gears (or I may stick w/34s when I replace the tires). I've heard a lot of good things about 4.88s w/35s but I still haven't heard of anyone running 4.56s on a JK.
Anyone running 4.56? What tires/transmission? Are you happy with them?
