Ok recently I made a post about the 9 bolt. Well I just got it in and it wasn't the gear ratio I wanted. Only 2.77. Sux don't it? Leaving me with no new rear end. Well after I purchased it I found out that there was a Dana 44 made for the 3rd Gen F-Bodys and they are supposed to be the strongest made. What firebird's and camaro's where these available in? So I might be able to find one. Also what gear ratio's were available in the f-body's? If they have a bad ratio's only like 2.73 will it be easy and relitivly inexpensive to put in a new ratio? Did they come with posi's and drum, disc or both brakes? And Last and very unlikly does anyone know where I can find one? Anyone seen one in their junk yard or local paper or just may happen to have one or has a friend who is willing to part with it? I know thats a long shot but I gotta try. Thanks...... Erik.

 

I'm pretty sure they only came in the 1992 Pontiac Firehawk. And there are only about 25-30 of those in existence right now I think. Good luck with your search.

Yeah thats what I was afraid of. BUT I have just found out that they were also put into the 91 firehark (prototype to the 92)Only 6 made. But also the were in the 89 turbo TA A couple hundred made. If anyone else knows what they were put into, let me know. I found out one gear ratio the came with 3.54. Are there any others? Also if you can help with my other questions Or can help me find one I'd really apricate it.

 

The Dana 44 was a dealer replacement item available from GMPP. Unfortunately it's long since been discontinued. Mine came with posi and discs. Your best chance is probably to just try the junkyard and hope you get lucky.

There was a discussion on this on another thread, and I believe the general agreement was that the Dana 44 actually didn't come on the TTA, or in fact any other factory thirdgen.

Hey thanks for the information. Sucks they were discontinued. However I did a little research on this and accoring to SLP engineering, the guys who designed the Firehawk, the 91 and 92 Firehawk's came factory with the Dana 44. I'm pretty sure about that. Also on a web page that I came across that was dedicated solely to the 89 Turbo TA said that it too came factory with the Dana 44. If I can find that page again I will post it here. It is hard to conferm this since those cars are rare and I have never seen one. I was just wondering if it was an option on a standard firebird camaro, Z28, Trans Am or anything F-body and what years? I do think that theses sources can be considered reliable especially since one of them is SLP and they designed it.

 

If you can wait until spring, DTS is coming out with a Dana rear for third gens. It will be about 25% cheaper than the 9 inchers from Mosers.

Gotta love the PRI show

Oh yeah I can wait till spring. I never heard of DTS. Do you have their internet address or phone # Thanks

 

I wasn't disputing that it came on the Firehawks, just that I don't consider those "factory" cars.

Sorry, I stand corrected. The turbo TA came mostly with the 9 bolts. I think they were just talking about the indy pace cars for that year. I could be wrong about that too. Thanks to all those who gave me the webs sites for Dana 44 distrubitors.

 

Not that this answer any of your questions.

About 2 years ago, I was looking for a replacement rear for my '89 IROC. Well my grandfather works for Dana and I had him do some checking around, because I saw the Dana 44 listed in a '96 GMPP catalog.

According to his sources at Dana, there were some 44s in early 3rd Gen F-bodies. Also that SLP had bought all the remaining stock of the 44s in '96 or '97 (that's why GMPP quit offering them).

Sparks a flyin'.

 

If I blow up my diff next year, I want to go to a 9" but if I can get a 8.5 dana44 cheaper, it would be sufficient for me.

Apeiron: Let me know if you ever want to part with yours. MMMM Ya. Your car would look real good with my 9 bolt sitting under it. 3.27 gears, posi, disk brakes. You can come and have a look at it if you want.

Just in case anyone's interested, too, the numbers I have for the GMPP Dana 44 axles were 14044853, 14044854 and 14044855. Don't have ratios for those unfortunately.

GMPP still stocks ring and pinion assemblies for them too:

3.31:1 - 14044859
3.92:1 - 14044863
4.09:1 - 14044864

Only trouble is, that 2.73 carrier of yours has very few gear ratios available. Richmond offers a 3.73 as the lowest gears for that carrier. If it was 3.73 gears instead of 2.73's then the lowest gear set available is 5.89.

Toms Differentials lists a thick 4.10 gear for a 3 series carrier (2.72-3.73). A 4 series carrier is 3.92 and up and a 4 series spool is available.

There's an e-mail address on my IROC web page.

 

Aperiron,
Are those part numbers for just the axles (why 3 numbers) or are they for the whole rear axle housing?

Apeiron,
Those part numbers, the last two are for gear sets. They are still available from http://www.gmpartsdirect.com for around $275.
So they are not for complete assemblys..

I did my own. Unlimited Performance will do it for you. They do a lot of the race cars and they set up the rear ends with pinion depth guages.

 

Ok, I'll give them a call. I haven't dealt much with the shops in town since I've been here, had my car on the dyno at Davenport but that's about it.

John, I just tried looking on gmpartsdirect.com and shows all three numbers are "not found".

I'm sorry. My cut and paste was screwed up and I pasted the numbers for the gear sets.
Has anyone done a globle search for the Dana 44 F-body axles with those part numbers?

I did a search on drive train direct's site. They list axles for just about everything but nothing for the third gen dana44. They'll make a custom set if you need them but I don't thing anyone here including myself will hurt the stock 30 spline axles. Maybe if you're running 600+ hp and using a tranny brake to launch at 4000+ rpm.

 

I was under the impression that the DANA 44 was also used as a warranty replacement for the BW 9 bolt.
