Dana 44 front, Dana 60 rear?

While looking at options for regearing my jeep I have found a source for some replacement axles which would include the gears I want and the electronic locker. Completely replacing the axles will only be slightly more expensive for me than replacing just the gears and adding lockers, so it’s a no brainer.

I’m just going to be trail riding, no rock crawling, and from what I can tell the D44 will be plenty strong enough.

The front axle that I want is the Spicer Ultimate Dana 44, but on their website I don’t see a 44 for the rear, only a 60.

I believe stock axles, which I have now, are 30 in the front and 35 in the rear.

My two questions are:
1. Is there any drawback, other than costing slightly more money, to running 44 in the front and 60 in the rear?

2. Does anyone know if Spicer makes a rear 44? I’ve googled it and the best I can tell is that they used to but called it something else but don’t anymore.

If you're gonna do all that, just go 60's front and rear!
I did the Teraflex 44/CRD60 combo on our '18 JK. No intentions on running a tire larger than 37" (on that Jeep) so IMO it was a great choice. We're a tick over 75k miles on that set up.
Now if the 60 is not a HP then you'll lose some ground clearance.
Also FWIW you have A 30/44 combo now, only a handful of 2007 JKs had a 35 rear, all others have a 44.

I’ll verify the rear on mine and see if it’s a 44. If so I’ll just get it regeared. Thanks!!!!

How much are shops charging you to regear that going with a new aftermarket axel is almost the same price ? Damn. I paid $1200 OTD for my regear 2 years ago. Locker was $2k rear only, done this year. Yes i should have done everything at once but that wasnt possible so I had to do it in stages. An ultimate 44 today for the front will be around $5k. In my case I'll wait 3 years and change to have the Jeep paid off, then I'll be serious about aftermarket axels and next round of serious mods. I do rock crawling though for now not the type involving Chocolate Thunder in Jonhson valley :) but definety the one that scratches/dent steel armor and the like. Once she's paid off the natural progression will allow me to take it to that next level and I'll go straight to D60's with long arms and big meats.

If you have a JK newer than 2007 (2008-2018), it has a Dana 44 rear. Re-gear it and locker it (personally I like OX lockers) will be cheaper than an ultimate 60

The quotes I got to regear both differentials, and add the elockers, was going to be around $5000. I now need to get a quote for just the rear.

The source I have for a new Dana 44 Ultimate front axle with the 4.88 gears I want and elockers is $3400.

In that case go for it. that's a heck of a price (y)

That is a good price, I paid that about a year and a half ago when it went on a flash sale on Amazon. It’s a really good axle in my opinion, it offers pretty much every feature the more expensive axles offer(optimized caster/pinion angle, bigger Cs, thicker brackets) , it’s not as strong as the others, but I think it’s a pretty damn good axle for the price.

if You don’t plan on anything too hardcore I would just keep your 44 rear, maybe add chromoly axle shafts, regear it and call it a day. I haven’t touched my rear 44 yet Other than regearing it. I don’t plan on getting rid of my 44, personally for my wheeling style I think it’ll be plenty for when I go up to 37s, I’ll probably just upgrade to chromoly shafts.

Regearing your stock axles should not cost anything close to replacing both axles. A regear front and rear should be $1500-2000 if you shop around. Let's say another $1000-1500 for a locker (although I don't know why you would need a locker for "trail riding"). So $2500-3500 total. Less than even one new axle, not even counting the cost of labor to do the axle swap.

Normally you’d be correct. But as I mentioned I have a source for a much cheaper cost (dealer price, not retail) which makes replacing the front axle the obvious choice for all the other benefits. And a friend is going to help me do the axle swap so no labor. :)

As far as the price you think I’d be able to find if I just shopped around, I got quotes from three different places around here for 4.88 regearing and elockers on both, and all of them were within a few hundred dollars of each other, around $5000

As far as needing a locker for “trail riding”, i’m not sure why you put it in quotes as though you imagine my trails as gravel roads with no obstacles. I’ve been going on some trails in the north Georgia mountains which are much more than just an easy ride. There have been several times when I did not go on the side trails that some other members did because I would not be able to get up the hill, through the mud, or whatever the obstacle was without true four-wheel-drive. I don’t even have limited slip differentials or anything like that.

Some of the people in the group I ride with have said they have broken axles on some of these, so it’s just a good precaution to go ahead and get rid of the D30.

I may not know as much as you, or most people on this forum, which is why I love having this forum as a source for information. Most other replies to my posts are normally helpful.

You are correct!! I just got home and checked the equipment list on my Jeep and it shows "Next Gen. Dana 44 HD Rear Axle". Not that I doubted you after you let me know, but it was nice when I saw it verified.

So the plan is to definitely just regear the rear and add lockers, and replace the entire front axle.

My guess is the order doesn't matter much, as long as I don't attempt 4 wheel drive with two different ratios.

Thinking it over I'll probably get the rear regeared first so that when my friend and I replace the front we can take it for a test drive right away, as well as get an alignment done.

And as soon as the 35" tires are ready to be replaced I'll be ready for the 37s, I'm guessing by the end of the year. I'd hate to throw away the remaining life on the 35s.

I guess I touched a nerve. No offense intended. I was just surprised by the math, but it sounds like you've done your research re costs of the various options. Being able to avoid paying for labor really helps.

Regarding "trail riding," I quoted it from your post. It could mean a lot of things, and your first post didn't elaborate as you now have done. If you think lockers would help you, then you should get them. Have fun with the upgrades!

Correct, as long as you do not engage 4x4 you can drive with 2 different ratios. I drove around with 4.88s in the front and 3.73s in the rear for a few weeks
