No, they're 35 spline inner and outer.

 

Jeez that's a heck of a deal breaker. I would much rather get one of them then bother with upgrading to 35 spline Detroit, inners, outers, and hubs on a older one.
All you have to do is put a locker of your choice in and that's one heck of a stout axle. Thanks for the info man!

 

you really don't need bigger than 37. I hang with guys on 40's all day and guys on 35's hang with me all day. tire size isn't incredibly relevant to overall performance. in fact I'd count it as one of the least important aspects. I'd rather have any sticky 39 or 40 over a bias 42 any day of the week
you would hate to spend all the time and money for only 1 more inch of clearance, I'd hate spending all that time and money trying to turn a Cherokee into a buggy lol.

mines still street driven too. if you're going to put something on a trailer it might as well be a full tube chassis. but hey, we're all on our own learning curve

 

Hindsight is always 20/20 when building something. If i had the lump sum of cash to build a buggy I would have. But I'm poor and I can build my XJ in steps so that is just what works for me.

 

Yeah I hear that, I guess it all depends on what we each want in the end. At my local ohv park there's a run called no winch hill. I'm building my xj to try and do it. It's kinda like a goal I guess. I see no way a jeep on 35s or even 37s could do it. Next time I'm out here I'll take some pics for ya. Y'all see that green s10 that won TTC last year? Rear steer, rock wells, 54" claws. It's about the only vehicle I can think of that can handle this trail lol
I'm sure a very skilled driver in say a small vehicle with 40s could maybe get up it haha

That's what I've been doing since I've had my xj lol

 

lol. this poor guys thread

 

Just my $0.02 on this.

35s under a Dana 30/8.25 have as much clearance under the diffs as bigger axles and bigger tires (sorry I have no real numbers lol)

I researched this for a long time, to swap or not to swap. I decided that for 35s and my moderate wheelin style that I would keep my hp d30 and 29 spline 8.25 with 4.56 gears, chromos, locked f/r.

If you're set on going bigger than 35s then I'd recommend a swap

 

you ever seen ultra 4 cars up against bouncers? they put bouncers to shame and they're only on 39's or 40's

gotta compare apples to apples. comparing a 37" tire to a 40" tire isn't far off. if you're talking an average build on 40's next to a rig on rock wells and 54's? yeah you might notice some subtle differences.. the TTC rigs are made to go through tank traps and other **** that a rock crawler most likely isn't set up for. at all. and vice versa. apples to oranges

but yeah take a picture when you get a chance

 

I talk about the TTC truck because I saw It out here 2 trips ago
Granted, it was parked but as I inspected that rig I thought I may do just about anything to own that truck lol turns out he's from Oklahoma and came to my local ohv park for a night ride. I guess he sold it and is now building a full bodied something or other to be more family friendly.
I've only seen a few videos of bouncers and honestly wasn't all that impressed...I'm going to try to keep my xj as intact as possible when it has tons under it. I just like the feeling of "no worries" running one tons. I could run about as big of tire as I wanted to without having to worry about breaking a shaft. Especially if I still had the trusty old 4.0 and just a 231 with a doubler or something
It's funny I see mentioned the bigger axle vs tire size up there.
I have more ground clearance Under my d30/8.8 with 35s than my bro on 14bt and d60 with 37s.
I'll just say this now, Sorry OP diddnt mean to jack your thread.

I go out there the 13th for a charity ride and will grab some pics of that run for y'all

 

What 37's are they? Did he shave the rear? I've got almost 12" to the bottom of my diff. I gotta tell ya, I get around a lot easier on the 1 tons than I ever did on my 30/88. I'm stoked to see your build tho man. Always awesome seeing another Cherokee go ***** to the wall

 

He drives a 1990 k5 blazer on CUCV axles. So locked 14bt ff 4.56 gears and a kp 60. They are the Kevlar mtrs on a 17 in wheel. Measure probably to 36. One thing I'm surprised about it my "35" km2s measure to like 33 1/2".. And that's at street psi
We wants to do the 13 bolt shave kit. He got hung on both his diffs last trip out and I had to winch him out
I might have 12" to the bottom of my diff...I know I've got about an inch more than he does.
And yeah I can't wait to put tons under it, he wants to give me his 37s when he gets 40s but I can't put 37s on the 30 lol
Next up is frame stiffeners, ruff stuff DIY long arms(I'm gonna make them radius arms) and a locker for the 8.8. If all goes to plan that should be done by the new year.
Your running the ruffstuff long arms right? I may have to pm you about how you did yours to get a feel for what I'm doing lol

 

ruffstuff long arms yes, radius no. go straight to a 3 link if you're gonna take the time to fabricate a kit. the 3 link performs noticeably better than the radius arms. you'll be happy you did it

 

JK Rubicon axles!

 

*Are a waste of time.

 

You mean the DANA 50 axle by Ford. All it is is a HD DANA 44 in a larger housing. Plus side, its a hell of a lot easier to find than a D44. Downside, 8 lug crap hubs.
