I don't know RPM range but if you have the v-8 go with 4.56 or if you have the 4.0 get 4.88s. I have the 4.0 and I'm kinda doggin it with 4.56s.
Id do 4.88s with he V8, that was my original plan. Doesnt rev all that high IMO and it sure feels peppy. 4.56s and the 4.0 definitly does dog it, especially at high elevation.
 
I am runnin 4.88's with 35's and a 4.0 and I havebeen running around 2300 to 2500 rpms in overdrive at 70 according to my speedo wich is 5 to 10 off, so when it reads 70 it is actually 60 to 65. But even still I am not pushing more than 2700 to 3000 rpms.

Thanks for the replies. I do have the 4.0L. Right now I have 4.56's with 265/75r16(32's) and run about 2500rpm at 70mph. I thought about 5:13's because I really want 37's, but might just settle for 4.88's. Checking online calculators...looks like 5.13's would put me at about the same rpms I'm at now with 4.56's, but 4.88's would close to stock.

I'm hoping you're not talking about 5.13's in a 30/35 combo turning those 37's...

Sorry, I thought that this was JU for a moment there!

Personaly I think you'd still be pushing those axles on 37's; big time. I blew the ring gear and 3 axle shafts on my 44 rear this summer, with 4.56's and 35" MTR's (Which are really like 34.4")

What type of wheelin' to blow your rear D44? Rocks are my guess?

Our terrain here is pretty mild no rocks, just mud and sand. I'm not to scared of the 9", 44 I have thought about, but will run it any and see what happens.
I think the shafts and/or u-joints will go well before the 44's ring/gear does. That said, I personally think 5.13s are just to much for the 44. But I have a V8 and live on the west coast...
 
I am currently running 4:11's and 35's and I have no problem getting up to speed.. I run about 2750 at 70.. Not that big a deal... I have the 4:56's ready to go in just havent had time..

Anyway.. I 5th the 4:88's for 35's ..Also wouldnt put the 5:13's in the 44.. You may rev a little high and maybe dog a little but the pinion gets awefull small with gears that steep... :eek:

Thats wierd, my 4.56's and 32's run a lower RPM than your 4.11 and 35's. I"m only at 2500rpm at 70mph.
