I'm trying to figure out if my Dana 44 is a GM sold Dana 44. I could not find any of the listed GM part numbers on it. The only thing I found weird is there is no hole for the brake line t in this diff. I will have to add one.

Thanks,

John

I don't believe anybody else produced a third gen Dana 44 except GM. The torque arm mount wouldn't be cast for some other model.

The only production car to get a Dana 44 was the SLP Firehawk. Every other Dana 44 had to be purchased over the counter until GM stopped providing them.

In my research I have found some claims that the aftermarket companies made bolt in versions as well. Also I believe the aftermarket 12 bolts have cast torque arm mount?

Bump. I know there are some Dana 44 owners out there.

To keep you from bumping this insanity again, I'll spell it out for you. No other models ( OF VEHICLES, NOT axles ) have the torque-arm. It's no great challenge to add torque-arm provisions to other axles, it took me one afternoon to fab one up for my truck-spec Dana 60 to go under my '84 T/A, and cost me absolutely nothing. Now that I did it once, I could sell kits for $20, except there's NO demand. Nobody but me wants a 500# axle under their car. ( I'm only doing it long enough to prove I can to a gooseneck trailer, then back to a 7.5" 10-bolt while I prep myself a Ford 8.8" axle from a Lincoln Town car )

I'm not sure what this has to do with whether my Dana is GM sourced or aftermarket. I never said there are other cars with torque arms. But to correct you, I think you will find the 4th gens as well as the GNX run torque arms. There are probably others as well.

Other than that, I will agree with you that you are probably the only member here that wants a 500lb axle.

Fourth gen were just carryover, still Camaro & Firebird, still same models, as far as torque-arm goes. GNX didn't get any torque-arm provision cast into the diff housing, it was a bolted on, rear-cover deal. GNX axle won't take F-car torque arm, and vice-versa. Now, you posted something about correcting me?

Yes, all those cars use torque arms. You said no other cars have a torque arm.

Any way, its clear you have no interest in helping. So I would appreciate you stop posting in this thread. Thanks.

Actually the GNX is different from other G bodies in that it does have a TQ arm and not the triangulated 4 link type deal. Just like Atilla says, it's bolted to the diff cover, it's not specific to the axle.

I am aware. None of this is on topic though. The fact is the GNX uses a torque arm. Thats all I ever said. Atilla claimed no other cars use a torque arm.

No other cars used a differential mounted torque arm in such that the case was cast with the mounting pad on it. The GNX is no different, it's the lid that is different on those, without it you will not be able to mount a tq arm to it, and even with it an F body arm won't fit.

So, share your "research" you've found instead of stating empty claims.

Various shapes and marks on yours that are still visible despite the paint look just like any other Firehawk or GMPP D44 out there. Look at the curved jelly bean shape at each rear facing plug retaining the axle tubes. Same. Dimples in the casting above and below to the right of the plugs. Same.

The odds of a company making a torque arm specific casting like that without selling a bunch is slim. Large volume aftermarket stuff ends up being "known," even if there are few surviving examples.

So, it's a GM rear.

The marketing and sales venues were SLP and GM. I don't know if SLP's sales through Summit included the D44.

Your question has been answered.

From what I understand, Dana had them ready to go for GM production but ended up with the cheaper 10bolt. GM did use them as warranty replacements for blown up 10bolts.
SLP started as a company around 87ish and they started gathering/using all the HD/prototype/players speed parts in GMs inventory including the Dana44s. Maybe even had more made since I've seen 91 date codes stamped in some.
They had a few prototype cars running around in the mid(87) to late (80s) testing the parts.
Then the Firehawk was born in 91 with a lot of the parts.
As far as another company making them? I highly doubt it but I'm not sure. Dana/spicer is the only place I know to make a dana rear.
I did notice your axle tubes are fully welded. I'm fairly sure thats not a standard thing from Dana.
Maybe yours was from a race team??

Thank you JMD. You are the first one to to look at the pictures. Its seems you have seen a third gen Dana 44 before. I never have, thats why I'm asking. Just looking to understand the complete story. I can't recall where I saw info regarding aftermarket companies also selling the D44's. I wouldn't be surprised if they just bought some stock from GM and resold them. I also wouldn't be surprised if the information was false, I believe is was a simple claim from someone on the forum. Its really not worth researching. Thanks for the help.

Thank you for an answer without an attitude. Who knew this would be such a touchy topic.

The previous owners claims to have welded the axle tubes. It had a 4.30 gear and a spool when I bought it from him. And it was in pretty rough shape, but I got it for a fair price. I don't really trust the seller at all, that is why I am trying to verify facts.
