Best rear axle??

Last night I picked up a Dana 30 Wide Track front axle for my future jeep build. So what is the best rear axle to pair with this front axle? Thanks for the assistance!

Thanks,
The CJ Noob

If you are talking about building a CJ7 and you don't have any rear axle now then the easiest rear axle to add in is a 72-80 Scout II rear Dana 44. It has a 5 on 5.5" wheel bolt pattern and it 58" WMS to WMS. The stock CJ7 wide track rear axle is 56"WMS to WMS.

I'm swapping out my rear axle with a Ford 8.8 from a 1998 Explorer. I'm installing the Superior Axle "Super88 Kit" as well as an Aussie Locker. The axle kit gives you the 5 x 5.5 bolt pattern that you need as well as a bunch of other nice upgrades.

But as far as the easiest swap...Like Bob said, the Scout II rear Dana 44 is the easiest option. If you can get your hands on one.

How hard/difficult is this swap? I'm really open for anything because I don't want to cut corners! So what can you share with me about the difficulty of this swap?

I found a Ford 8.8 rear axle out of a 2000 Ford Explorer for $300. It's a complete rear axle from end to end. The gear ratio is 3.73 but that doesn't matter because I wanna regear anyway. Is that a good price?

A super 8.8 is going to cost nearly $1,000 when finished.
And that's doing all the labor/setup yourself.
Not a great choice in my opinion.
A direct swap 86 Cj D44 is near half that.
And the Scout D44 can be had for $200 all day long.
Hell, you can have a custom built 9" Currie housing with scavenged parts for the same price as the 8.8
Or if you can find a D60-2

and it all depends what your building your rig to do and what tires your going to run.

Well what are the perks of using a ford 8.8 rear axle and I will probably never run bigger than a 35-36" tire

Yes, They are, But when you buy the $600 88 kit it comes with the 5x5.5 pattern.

By itself, Non.
Built, they are okay, But not the best choice.
The 8.8 with 4.10 lsd and discs are the better to buy.
Add the $600 88 kit and driveshaft and you'll be mediocre alright.
And don't let the large axle tubes fool you, Because they really neck down.
BTW: The 8.8 is 6" wider than a WT AMC20

for 35's run a medium duty axle like a ford 9" or d44. reason being, if you go to a 1 ton axle such as a d66 with 35's, it will drag over everything.

If you buy a scout Dana 44 axle you don't have to do anything to it except move the spring perches to make it work with a CJ7. The Ford 8.8 axle will require that you change the shafts to get a flange that will fit a 5 on 5.5" wheel pattern. A ford 8.8" axle also has a round flange pinion yoke that you will have to deal with. The Dana 44 scout axle has a standard 1310 pinion yoke.

Another vote for a Dana 44. I got one out of a scout. I picked it up complete with the front axel shafts for $150 though it had to be completely rebuilt but it did have 4.11 gears. I filled it will spicer gears, Detroit locker and moser axels. I got 35s and 350 HP to it. Word is that Dana is doing crate axels now. Not sure what specs you can choose, but intriguing non the less.

I know a few people that have done the 8.8" but I wouldn't do it without the c-clip eliminator.
