Wide axles? Yay, or nah?

I've been looking into some axle swaps for my '89 Cherokee. Now I would like to 4link the back, as well as just run coil springs. I have an 8.8 and Dana 35 non disco. My question is, is it worth it to go to full size axles? I want to eventually run 35-37 inch tires. Dual transfer cases and the correct gearing. Will the motor hold up to running 37's? And how much lift will I need? I don't want it to tall, but I am looking into a slight front wheel base stretch. If I got full size axles what's best? I'm a Chevy guy at heart, but will a 12bolt rear hold up as well as a 14 bolt? If built correctly? Or just go with the standard Dana 44 front and FF14 in the rear?
I live in Oregon, and still plan on daily driving this jeep even after full size axles are installed however, I'm not afraid to wheel it hard. Mostly trails and such are around this region. Want it built as solidly as possible though

Will the motor hold up to running 37's? yes
And how much lift will I need? enough to clear and articulate, without being too tall
If I got full size axles what's best? 60/14ff
will a 12bolt rear hold up as well as a 14 bolt? no
If built correctly? why waste the money to do it twice?
Or just go with the standard Dana 44 front and FF14 in the rear? yep, at least.

If you really want the cheap(ish)/ smart route and plan on not larger than 37s, go mid-width with JK Rubicon axles and modify them as required.
Heck, the Dana crate JK 44 axles are pretty much dirt-cheap compared to properly building 1-tons and they already come with large brakes, e-lockers at both ends, and gearing available up to at least 5.38

I was asking because a Dana 44 and FF14 came up for sale at about 500 and I wondered if they were worth it.

If it really is a full floater rear 14-bolt, then go for it. Even though 14-bolts are dirt-cheap (even here in Finland ), and full width D44s aren't that rare either, it's still a good price.

Just make sure the D44 is a drivers' drop, unless you want to start grinding off plug welds and re-tubing the front axle.. which you most likely don't want to.

So mainly speaking besides the strength, how much wider does it make your jeep compared to stock? I have a Ford 8.8 that I've been waiting to put it till I could decide what I wanted to do.

Full widths are considerably wider, some "mid-widths" are around 65", but most 1-ton axles are around 70" WMS-WMS.

SO you're looking at about 10" width increase.
