Factory Dana 44 With 4.10s and a Torsen?

If anyone can help me here, it's the Hive. Do y'all know of any factory vehicles available with a Dana 44, featuring a 4.10 ratio and a torsen diff? I'm bench building an eventual bronco purchase and that kind of diff would complement the 4.10 trakloc available in the back of a v8 explorer I have planned for the rear. My current option is the open 4.10 D50 found in the front of old F250s. Not a terrible option for a cheap regear but more traction is more better, right?

Edit for clarity: I'm only concerned with the diff from a D44, not the whole axle. The D50 diff in front of an old F250 is a bolt-in upgrade to a deeper gear ratio. The v8 explorer 8.8 diff is also a bolt-in upgrade for 4.10s AND a clutch-type limited slip.

I started thinking of rear axles before i realized you wanted a front axle. Selectable locker isn't what you're looking for, i guess? Are you going to run manual locking hubs?

In reply to Vigo :

It's just the 3rd member I'm concerned with. The TTB in front of a bronco is just a weird D44 axle with extra joints.

I do plan on manual hubs. No selectable locker, just looking for a cheap way to get a helical LSD up front. 

I'm thinking the 4.11 will be the biggest problem to buy as a factory part.  Thats pretty steep.  Easier to find a 60 with that ratio, which does you no good at all.

I can't think of a factory front D44 torsen at all. How steep is a new one? I looked at them for my D30 but forgot the price I saw.

New is like $500 for the diff plus gears and install. 

most solid d44 front axles no matter the gearing are fairly expensive used.  it will likely be cheaper to just buy the gear and locker new.  And i dont think you will find any in 4.11 with lsd's for front axles, the military trucks will likely be 4.56 or lower and will be trac-loc style lsd's

I'm assuming you just want the Torsen that can accept a 4.10 to use in your existing front diff?  If so, remember that there are "thick" gearsets that allow you to use a differential from a 3.73  and lower (numeric) carrier break.


The 2012 and up Raptor used a Torsen and 4.10, but I'm pretty sure it's not a D44.

In reply to Cooter :

No, the goal was an LSD with the gears done. Gotta save that money right?

That's not going to save you any money.  

Depending on the Bronco you are talking about, and the Explorer, you are going to be fighting width, suspension, lug pattern, and front driveshaft issues.   The gear setup is going to be the least of your worries.

In reply to Cooter :

reads like they are staying with the ttb d44 that came in the bronco, they just want a 4.10 lsb.

But you would still need to find a TTB  D44 center section.   Which is just found under Fords.

And since the Explorer 8.8 is 5 on 4.5", you will have a lug pattern and width mismatch with the 5 on 5.5" lug pattern on the TTB.


Unless... we are talking about a Bronco II.   But then, that is another whole can of worms.

I'm assuming the front diff/3rd/chunk is the same as any other D44. That's all I'd be swapping. To be fair, I'm fully expecting to fail in this quest. But, if anyone knew of some oddball diff, it's someone here. 

The rear is handled by just swapping the diff front the Explorer. They're both 8.8s with the same spline count so it bolts right in. 

I see how my first post wasn't very clear on my goals. I've edited it to rectify that. 

D44 TTB is reverse cut high pinion and nothing at all like a d44 rear.  If you have 3.55 like almost all of them then to go to 4.10 youll have to change carriers so you may as well get a detroit or lunchbox locker.  As was said above, the Exploder axle gets you discs but is narrower and a different lug pattern.  Ive been running 3.55s with 35/12.50s for 8 years successfully,  rock crawling, towing hauling etc but my 96 also has an efi 5.8 mass air engine.

Your best bet is to find a D50 chunk on a 2/350 (dont forget the stub shaft and c clip mod) with 4.10s and swap the gears in your 8.8 rear.

then there also is the D44HD that is in some F250's as well which is also a ttb front but is bolt in stubs rather than c clips.
