4.56 if those are the only options - and that was too much for mine w/33's. I'd go 4.10 if I had to do it over and I was going to run 33's. I am running 4.56 w/35's and is perfect for a dual purpose DD/Moderate off road set up IMO.

My childhood was typical. Summers in Rangoon, luge lessons. In the spring we'd make meat helmets.
When I was insolent, I was placed in a burlap bag and beaten with reeds. Pretty standard, really.

I'd definitely go 4.88 if you are *sure* about that top speed and you are leaning more towards a trail rig and "around town" Jeep than a highway/freeway cruiser.

You'll be at 2600 RPM or so @ 50mph w/ 4.88's.

Well, I run 4:88's with my 33's and a T5 tranny.
Love'em.
Really don't think it would be worth it with a 4 speed to go from 4:56 to 4:88.
For trail use, in this case. I would go to a 4 to 1 t'case, and stay w/4:56 R&P.
I have a 4 to 1 t'case also, sure makes "rock'n" easier for sure.

I have G2 sets in both my 2003 F350, amd my 1983 CJ7.

Did the F350 in 2008, and CJ in April of this year. No problems with either one, and I put between 20 and 30,000 miles per year on the Ford, often towing 15,000 lbs.

My opinion...they are gtg

AMC 20 1 less spline, at 29.

The weak points are the 2 piece shaft to hub, the possibility of spun tubes in the center section, and I believe lighter weight tubes.
