I don't have a super kit in the 30.

Stock shafts, stock ujoints, HP30 from a cherokee.

My super kit is in the rear axle.

Check out the DuraTrac if you're going to be on the highway a lot and off-roading from time to time. They come in a 35" version.

I have seen those. They are awesome. I have some 32" MTR's from the budget boost I use for daily driving. It's not a daily driver as my company saddled me with a car. I swap the 33's in for wheelin but in reality the MTR's are probably just as good as the ProComp Xtreme Mudds if not better. When both sets are done I would have a tough time not buying another set of MTR's. I have close to 20k on them and they are far from finished.

I have the old style MTRs and I absolutely love them...but they are a discontinued tire (which makes no sense based on their popularity) and are becoming very hard to find.

When looking for a HP Dana 30 does it matter
-Year of the Cherokee
-ABS yes or no (Assume no as my rig doesn't have ABS currently)
-Gear Ratio (4.10 would be nice but should i trust junkyard gears?)

Should this be posted in a new thread? Dumb newbie I know.

Also how much should I expect to pay. I have been seeing 250/300 up to 800. Whats the going rate?

Front Axles
Dana 30 high pinion - reverse cut - 27 spline, 1.16" diameter shafts, 7.13" ring gear - used 84-99 (some axles through 91 are vacuum disconnect, 92+ are non-disconnect, 89-95 with ABS have 5-297x u-joints, all 95+ have 5-297x u-joints, all others have 5-260x u-joints)


You want a non-disco housing with the 297x ujoints (95-99). I took mine from a 96.


Gear ratio is easy to figure out. Spin the pinion yoke and count how many rotations to turn the hub/wheel/rotor one full rotation. 4.1 turns of the pinion to 1 turn of the wheel = 4.10

Don't fret over not finding them. There is nothing they do that the new ones don't do better and a lot better.

I took Gerald's 35-17's up some steep dirt climbs out behind the house that I would have needed to air down the old ones for and didn't even slip a tire.

to the OP; I have a set up close to what you listed:
-04 Unlimited d30/d44, automatic
-4:56 gears, ARB's front/rear, Superior axle shafts in the front, superior tube seals upfront as well, JKS lcs skids running 33' KM2s.

The only thing I'd change is I should have gone with the hp d30 but I didn't do my research

However, I'm pretty happy with my set up, I've been able to run the Rubicon, Moab (the hardest trail was Cliff hanger) where I drive there, wheel hard, and drive it back home (no cash for a tow rig), with very minimal problems. What you might want to also consider is adding some bracing to your axles as well:the rear UCA mounts, the passenger side UCA mount, and front lca skids. It may not happen often but from personal experience, I have cracked or broken a few of these on the trail.

Thanks Apex and Surf. All good info. The salvage yards around here think their parts are made of gold or something. I found a D30 from a cherokee on craigslist for 100. The lady who posted it knows nothing about it.
Most importantly I want a non-disco housing with the 297x ujoints (95-99). Is there a way to tell whether it's a non disco and a way to id the ujoints?

3.55. And it came from a 1991 police cherokee.

It might have a vacuum disconnect.

I assume this is what I want to avoid. I realize they can be worked around but the non disco's should be easily available right?

I've seen good things from those new style ones. They most likely will find there way to my Jeep when the time comes.

You can block of the vacuum disco with a block off plate. Some people don't have an issue with the disco housing, I could go either way...the non disco housings are just easier to work around and plenty easy to find.

Do you have a local u-pull yard? You might be able to find one for cheap if you pull it yourself. And keep up on craigslist postings too.

Sent her a pic of a Vacuum Disconnect and she says it's not. It would suck to drive 100 miles to get it and find out she was fos.

Is this money well spent?

I'm actually waiting for axleboy (local shop) to contact me. He has been on vacation and asked me to wait till Monday when he gets back into the country so he can work on it.
The craigslist axle is a HP D30 non disco for $100. it has 3.07's
I'm leaning on regearing the rear axle and adding the ARB. using the stock axle shafts for ease of spare availability.
Same thing in the front except might get the hp 30 housing first.
Could always get heavier duty cromoly shafts.
Here is what i'm expecting:
ARB's front and rear 1600
4.56's front and rear 400
Labor 1000
HP D30 housing 100
Hopefully i can get a free compressor still
3100 for lockers front and rear and a stronger front axle

Is this money well spent?
