changin gears on a 88 MJ

MJ88SB · Jul 12, 2007

Hello

Nation!! It's been a bit since the last.

I've got stock 3.07 gears in my stick 4.0 4x4. running 31's.
My nephew's 92 yj has stock 4.11's that is swapping for lower 4.56's
1) Would those 4.11's be an easy swap for my MJ ?
2) If they do how much would my rpm's be @ fwy speed? :sure:
Right now i'm running @ around +-2100 rpm @ 65 mph.

Like always thanks .

I dont think its good to use used gears... its better to get new ones.

You'll probably love the 4.11s. I'm running 4.11 axles from a 4-cyl XJ and 32s and its just about right for highway use. If you have a pull-n-save place near you it might be easier to grab axles from an XJ 4-cyl since the front is a straight bolt-on, but the back you'll need to move the spring perches. Fpr the new rpms 2100*4.11/3.07 = 2811 rpm which is fine.
