Reading the required for a dana gear swap,they say a case change is required if going from 3.55 to 4.56? Are they talking about the carrier or the housing?The housing makes no sense to me, I know some 3 series carriers will not take a4 series gear.Can someone clear this up for me?

Thanks 1HB

Housing-


Carrier-


Yes you will need a new carrier, since I'm assuming that you're talking about the 30.

Dana 30 carrier breaks are 3.54 and down and 3.73 and up
Chrysler 8.25 does have a carrier break, but it's in the 2s, so not an issue for us.
Dana 44 carrier break is 3.73 and down and 3.92 and up

what is the best gear ratio for a dana 35 if im gonna run 35 in tires, and do i have to gear the front axle for when im in 4wd?

A 4.56 or 4.88 would do you well and yes you have to do both diffs.

Yes you MUST do both if not you will shell your T case

.....x 3.....you must gear both axles..... You will hear this again and again..... not the best idea to run 35s on a 35. BUT I'll tell you that many people have...with success...depending on how they wheel. I'm on my 3rd build now and am not taking the chance. Do a 44 or 8.8 swap. If you go with refurbished ones that are bolt in....it'll run you a good penny. So go JY hunting. If you're on a strict budget.....even finding a mid 96-99 29 spline 8.25 would be better.
Try searching on here and NAXJA....even JF. There's tons and tons of great info about axles and tire sizing.

The dana 35 by far the weakest of the 4 chy 8.25 dana 30 and dana 44
Dana 44 the first choice...but are not in abundance and will cost you a good chunk. Not sure about the 8.8 as I am some what new at my old age to the jeep thing,others can and will give you more info.

How can u tell if u have a 35 or a 30 etc? I know mine are 8.25 with 3.55's but I'm not sure how to tell anything other than that.

well if you know you have a Chryco 8.25 then only thing left is the front axle which is a High Pinion Dana 30....

X2 no 35's on a turdy five! instant busted shaft if you have a heavy foot

and every body discredits the 8.25, It's really a strong axle. the axle tubes are larger diameter and thickness than on the Dana 44, and the shafts are pretty robust, especially the 29 spline. PLUS they're a direct bolt in and pretty easy to find. The ring and pinion are comparable to the 8.8 and with alloy shafts can be as strong or stronger than a D44....
