gear ratio?

i havent visited in a while because money ran out on my jeep project and had a new addition to my family. my baby girl was born sunday.

but i now have money to spend on the jeep. im going to put a 350 in w/ ax15 tranny and an np231 transfer case. im goin to put a dana 44 in the rear w/ 35'' mtrs. my question is with this setup what would be a good gear ratio? i had thought to run 4.88. the jeep is going to be a weakend warrior, but i want it to be able to be economical as much as possible on the hwy. if you have any suggestions i would appreciate it.

thanks
david

ax15 tranny? anyways 4.88's sounds really good for 35's...but i wouldn't say it will be as economical as possible on the highway!

edit-sorry forgot your puttin a V8 in there. i was thinkin these gears would be for a 4.0...i think the gears would be different for a V8 (maybe higher than you would put in the 4.0 with same size tires)

thats the site i did most of my research at and have talked to them about the setup i chose, but i didnt find anything on the site about what gear ratios to use. it may be there and i just missed it. if it is let me know and i will try to find it.

was the ax15 a bad choice? i couldnt decide between it and the t18 or t19. i really dont want to use the nv4500 but if it is a better choice i will. i was trying to get the 5th gear overdrive for the highway.

i do have another question (sorry) how much lift do i need to clear 35s i was goin with a 4'' lift but i thought it might not be enough. would it be better to run a 6'' lift or a 4'' lift with a 1'' or 2'' body lift to clear the 350 engine?

any suggestions is appreciated.

thanks

no problem dude. ask all the questions you want. to be honest i've heard that the ax15 is a weak tranny which is why when someone is buying a used TJ they will sometimes try to go with 2000 and up to get the NV3550 tranny.

doesn't the NV4500 have overdrive? it is incredibly strong and can handle V8 power for sure.

well for a TJ you could get away with 35's and a 4" lift. but with the YJ havin smaller fender wells i would do at least 5 inches of lift. 4" suspension and 1" BL...now you probably will rub a little at full flex.

You may be able to fit the 35's if you do some fender trimming with a 4" lift. I am pretty sure that I can fit 35's on the front of my Jeep with a 4" lift now that I converted my front fenders into flat fenders. I need to do some trimming in the back now.
