Will this Chinese Dana 44 locker fit my Dana 35?

OP is in Italy. I have to admit, I'm ignorant to the conditions he's driving in.
Well Italy is a tiny country, but you can find any condition, actually. I live in the north west of Italy and during winter it gets snowy in the surrounding mountains, but the TJ spends 99% of its time in the garage during the cold season.
I drive it most on dirt roads (very bumpy full of gravel sometimes) but nothing serious, at least for the average wheeling trip I see on this forum or on the most popular jeep channels on YouTube. For reference this is the worst trail I’ve been on so far few days ago

To give you the flavor of the off-road driving scene here, I would say that the most common rig is the Land Rover Defender, then Suzuki Gimny, then JKs and JLs and finally G-Class
 
ARB posted the tests on youtube, have fun searching, their videos are pure propaganda bull and I've seen enough to last a lifetime.
Remind me never to share my comparison I did between our stuff and the fucktards who did a very poor job of knocking them off.
 
They knocked Yukon in a video and I've never heard you say they are a bad locker. I see their videos allot like those control arm bushing videos, highlighting something that really doesn't tell the story in a way that will help the consumer.

You've once said all the available lockers were pretty much equally reliable on the trail. I assume you don't include the Chinese knock-off because you haven't had any experience with them but you know what they say about assuming...
 
Why? Do they come with a free booster shot, masks and hand sanitizer? There are much better options out there.
Two lab rats were talking and one of them said “ Have you had your COVID-19 shot?” And the other one said “ No I’m still waiting on it to be tested on humans. “

That’s funny.

That is funny and the rat can get his shot today, it was just approved. Good timing.

I have zero experience with the China lockers you asking about, it seems nobody here has first hand experience with them.

Price is good.

I look at things like what is the risk to saving money? Does failure hurt me or could hurt/break lots of parts?


Do I know of said company and lots of positive experiences?


With a locker, if it fails it can cost you big time. At minimum, ruin your ring and pinion, bearings, possibly the axles. At most, your entire Jeep if it locked up and rolled you in the wrong place.


So, $300 seems like a great deal. Much better than say, $700-1100 for known good selectable lockers. But what does your ring and pinion cost? Bearings or master install kit? Shafts? Labor to do the work?


And say, it all goes south and rolls your Jeep. At minimum your Jeep is fucked. At most, you might get seriously injured or die.


Sorry, I’ve bought cheaper parts before. But lockers. Nope. ARB in most all my rigs.

Never an issue. In fact, I threw away all the spare line, o-rings, junction blocks, switches and other bits to repair them. I carried that crap for 20 years and 5 rigs. Never used them.


Not saying there are good lockers that aren’t ARB….and I know there are a few.


But I wouldn’t save that little of money on such a critical component. And for you do, they tru-trac is a GREAT option. That trial looks like many of my former driveways. 😂
 
I understand that, but a TrueTrac is also a proven traction control device and would also likely be beneficial in your use. Despite @pagrey's thoughts, it's a significant improvement over an open diff. As evidenced by the video below and numerous others the driver has posted. It also doesn't suffer from the issues associated with running a locker in a 35 without a Super35 kit.

I don’t think that video shows much of anything related to traction control devices. I didn’t see a tire off the ground which is where the weakness of any given traction device will usually be exposed. From what I saw in that stretch he did, I would’ve opted to go through that without turning my lockers on & I’m pretty sure I’d have gotten through it as he did but on straight up open diffs. In the other videos you referred to does he show wheels off the ground?

A stock non-Ruby TJ is amazing capable, particularly when all four tires are on the ground.

I think it would help if you understand who Yukon is. What they are not are inventors, designers or originators of good products. They are very good at sending shit through their various overseas copy machines so they can reverse engineer them, knock out some costs, and sell a cheaper imported version of what others have.

Get in touch with them and see if you can get them to tell you of a single product they have that is Made in USA that is not something out of a kit like a u-joint or bearing.

They recently (past year or so) started selling their own line of Made in China gear sets. I know from my local gear setters that they are crap and they no longer try to install them.

While the Yukon Zip may be reasonably (emphasis on reasonably) reliable, it is not their original design, it is a copy of ARB's older design.

Yukon only has one product I use and that is the hardcore hub kits. However, it is finicky, difficult to set up if you don't know what you are doing, and the running joke (well earned) is who originally designed it because it is too good of a product (once you get it working) for anyone at Yukon to have come up with.

Further, I set up our brake kits to work with the Yukon hub kits which were purchased from Warn. Since they have been taken over, I can no longer build parts, put them on the shelf and send them out as reliable fitting parts. Their production QC is all over the map, the bearing hubs wobble, the holes for the lug studs are at best a solid guess. Their answer to getting a stud to go into a hole that it is too big for? Get a bigger hammer. (I shit you not)

So now I get to have the brake customer send me his hub kit, I get to mock it up and solve the fitment and machining problems, make it all play nice together and then ship it all back. I spend an average of 3 hour per kit doing that and since I don't feel it is correct to punish my customer for Yukon's bullshit, I do all that for no additional charge, just a straight pass through of machining costs.

Still think I have no experience?

Don't get me wrong, I agree wholeheartedly that no limited slip can compare to a locker when a wheel on that axle is off the ground. However, I disagree with your premise that an open diff is as effective as a limited slip in maintaining traction and forward momentum in difficult conditions when both wheels are on the ground.

But it can be with just a little driving technique added. Drivers learned that technique out of desperation because when cars were in their early days, few roads were paved so getting through mud etc. was a real problem. They soon learned that applying the brakes to the axle with the spinning tire gave more power to the non-spinning tire which could get you moving again. That is essentially how a LSD works, it just couples that spinning tire to the non-spinning tire to give it more resistance, much like using the brakes does. Stepping on the brakes can also help a LSD work better since LSDs aren't totally effective in such conditions either.
