Dana 50 differential options

What have you guys done for diferential options in your Dana 50's? I would consider a mini spool or ez locker. I am running a Detroit locker on my 79 F350, I just lock one hub until absolutely neccessary. I use the 4wd seldom and I dont abuse it. I just want an absolute lock if I choose to. I only want a drop in unit.(mini spool or ez locker)

It's going to be tough getting any answers on this one, I bet.

Most people don't like full-lock of a spool on the front-end because it makes turning VERY difficult.

What do you mean by "lock one hub"?

Iirc the dana 50 is basically a dana 44 center section with dana 60 outers. I would contact randy's ring and pinion. If you are using this on a heavy truck you may encounter issues. A e-locker or arb would be a better fit and give the desired spool effect but allow it to be a open diff to turn. The dana 50 was used in the f250's that had twin traction beam suspensions from like 1981-1997

The dana 50 has almost nothing in common, parts-wise, with the Dana 44. The housing is basically a Dana 60 housing, and even then, nothing in common between all three.

the ring gear is 8.5 which is the same as a dana 44. The shafts in most models of dana 50's are larger than the dana 44 and smaller than the dana 60. It is more or less a ******* axle.

Good point.

--

Lubbockguy1979, not to belabor the off-topicness, but the D44 is an 8.5" ring gear, the D50 a 9", and the D60 a 9.75". Reason I know is, I used to say the same thing about the D44/D50 and I was proven wrong

I think he is referring to using manual hub locks, and locking only one. A low budget way to get a selectable front locker.
Basically, start by lincoln locking or spooling the front diff and then install manually locking hubs.
For steering ease, lock only hub. The other hub will be freewheeling, allowing steering.
For max traction, lock both hubs.

I much prefer this over open or even typical LSD. With open or average LSD, the power goes to the wheel that spins first - the one with less traction. In other words, if either wheel goes airborne, you just loss all (or in case of LSD, pretty much all....) drive from front axle. The exact opposite of what you want.
Using this technique, the driver selects which wheel gets the power. I usually lock the driver's side, and then drive (pick lines) knowing the left is the power wheel. If I have to go over a tough obstacle where I believe I need to have power on passenger side, I lock that hub instead (or both).

Kind of annoying to have to get out and manually twist when needed, but a WHOLE lot cheaper than ARB or E-Locker!

It's not a problem at all if you tell the girlfriend to get out and lock/unlock the hubs!

Heavy truck, mild power, weak shafts and aggressive fourwheeling... It adds up.. Broken parts.. Yup.

Hey guys, sorry for the lack of info. have a newborn that was in need of attention so I made the post quick.
1999 Superduty, F250, V10, Auto, manual transfer case with manual locking hubs.
Yes lock one hub for steering purposes. Both hubs only for short, straight, last resort option (three wheel). I have a 79 F350 with detroit lockers front and rear. Been doing the one hub principle for ~15 years.
No hard abuse intented.
I have heard rumor of being able to convert the 50 to a 60???
Thanks for the quick replies. I am being cheap....(fine line between cheap and poor) I found a Powertrax for $300, just dont know much about them. I was hoping for a mini spool for ~$100. This site offers alot of options that are not available through normal channels

You can swap an entire dana 60 front-end from a later model SD (late 2002-2004) into that '99.

That would solve a few problems all at once

The dana 50 30 spline axles are the same as dana 44 , I have used a 44 case in a 50 with some minor machine work. The axle are unique.

The Cover : dana 50/60 same

There is no way to "convert" a 50 to a 60. other than a complete axle swap.

Go to pirate 4x4. There are a few guys that have built a "poor mans dana 60". Btw the 79 f350 has a lot beefier axle under it. It should have a king pin high pinion 60. One of the stoutest axles in a pickup truck for the front.
