So in the event that my Cuda sells, I am thinking about putting my Duster back on the street. To do that, I have to put some smaller meats on it. 33x16.6 is a tad big to try and street.

My thinking is I probably have to have longer housing tubes to go to smaller tires, but keep the 4-link the way it is. So my question is, has anyone used one of these aluminum housings in a street strip 700-800hp car? It would save me a bunch in welding costs, and what's left, I can tack new brackets on the tubes and have them finished at a professional welders place. Anyone used one? I know the roundy round guys use these, so they must be able to take some abuse.

Never seen that before, It looks nice and beefy, and priced IMO at a great value. It looks as beefy or beefier than my similar style Mag dana.
The steel brackets are for the Roundy guys to attach various links, or to beef up the design or some weakness?
Seems maybe a tad porky? Shipping weight 29lbs?
I would love to measure one to see if any adapter plate is possible to incorporate an 8.75", which I seriously doubt. Hope springs eternal.

So I like that...I went and did a search, and can't find any modular Dana 60 centers....Is that a one off, or somthing no longer made?

Also looks like the one I found, they take it a step further....

Looked these up since I was looking at blingy parts for $2736...

Why not just order a sheet metal housing from any number of sources out there?

I'm sure that housing would work just fine. I've never used that exact brand but I did help a guy who had the MW modular housing. That setup was super beefy and very easy to work with. Expensive, but really a cool way to put things together.

I don't know the exact history. I believe it was a late 60's item, there are others out there, but are rather rare.
Can't believe the Dana Mag unit is in the same class strength wise as cast steel, but in my application for a streetcar that is OK by me.
I will be setting it up as a 3 link, so the modular design is very useful for me.

Hard pass.

And you wont be getting it a Summit or Jegs either. They kicked these hacks to the curb.

Hmmmmmm

Decent starting point for an IRS set-up, but not sure what advantages it brings other than cool.

Much stronger than that unit. I think the ends would flex with that Chinese built crap

The Mag DANA housings were a child of the early 70's and very limited production. they have a limited life span as they have the traditional corrosion issues plus they move around quite a bit (Flex) creating gear wear issues. I wouldn't do an aluminum center on a street car IMO. especially a Speed master

Looks like cast aluminum to me

I remember years ago seeing one of those mag Dana 60 in the back of Don Garlits pickup at Pomona way back a longtime ago, maybe 194/1978 era, I said man would I like to have one of those for my car (1970 Cuda 4 speed Hemi stocker) and he said no you don't, it is broken

My message is Mopar had them made and gave them to several professional racers and they didn't live so that stop them being develop further

That would be my thinking about the one I have. I would never put it to hard use, even the caps look wimpy, but it sure is light.

I guess they lied. Summit backtrack too?

So you are saying none of you shop at Harbor Freight? None of you put cheap chinko parts from Napa on your cars when you need a ball joint or somthing? Why hasn't an American manufacturer stepped up? I mean we have every kind of budget aluminum head on the planet now...but no rears....Not building a whole new Dana.

No I dont....Unless there is ZERO options which is rare. The racecars get only American made parts period. Its not cheap but at least I know the $$$ stay here. There are plenty of American manufacturers of sheet metal housings. From not terribly expensive to outrageously expressive. There is also Mark Williams and Strange who both build modular housings, if you feel you have to go that way. There is also a manufacturer of Billet housings if you really wanna spend money.
