small rear axles?????

Lots of companies are building their versions of the Ford 9" axle. Are their any companies that are building new custom nonQC axles smaller than the 9" for 4cyl or 6 cyl hot rods?????

I currently use some Ford 6.75 Pinto axle but would like something newer.

 

Not new, but plenty around with a very vintage race car feel - Alfa Romeo 105 series (1966-1994) rear ends, aluminum center with sump, disc brakes, 4 on 108mm, but the earlier 101 series Giulia Models (1960-1965) had drum brakes. They have a wonderful old time look to them and are good to 250 hp for sure. The rare Alfa Montreal model had rear differential oil cooler.

I just bought a bunch of these to use under my Willys 77 as they are 1/4" narrower than the stock Willys 77 rear end. 53" disc to disc. Most common are from the 1970s and 1980s Alfa Spider and these have a limited slip (posi) differential and 4.10 final drive.

You might be well advised to buy a driveshaft too as these are a two piece slider type with about 4" of play and so are readily adaptable to different applications.

 

Thanks, Weasel, Those axles are nice.

If you are an Alfa guy, you might be interested in my new Alfa engine Indy roadster.

 

Killer roadster and a nice variation on a theme. I've have always had a soft spot for Alfas - I've had several and consider them to be vastly underrated. I have a couple of 4 cyl Alfa engines awaiting their turn for hot rod duty.

 

That is a cool rear end!

 

That engine wood look super cool between the rails of a fenderless hi-boy !

 

Yep, the Italians are genetically and psychologically incapable of making a purely functional item. With the Italians it has to be art!

 

Weasel- how are the transmissions on those Alfas?- considering what you've shown, the right donor car might have a LOT to offer!

 

Oh, I forgot-

What kind of prices would one be looking at:

Engine
Tranny
Rear
Complete car?

 

Mac the Yankee, I sent you a PM. I do not want to derail Mac Miller's thread more than I have already done.

 

Actually, I'm using the Alfa 5spd that came with the engine.
It works just fine in the Indy roadster.

 

Back on the initial topic, I am pretty sure that Currie handles eight inch Ford rears, as well. A little lighter than the nine inch, but not really what you would call lightweight. Neither as artful as the Alfa rear.

 

I have a Ford 7.5" axle out of pre 92 Ranger pick-up for the 32 Ford I am building.
It is 56-1/2" wheel mounting flange to wheel mounting flange.
Stock it is the modern Ford pattern - 5 bolts on 4-1/2" bolt circle
With the 9" drum brakes it weighs 155 pounds, without brakes, 130 pounds.
With a little looking you can get 3.08 to 4.10 ratio out of the salvage yard.

Whats that width on the Pinto 6.75" wheel bolt surface to wheel both surface??
You have a weight on the Pinto axle??

Weasel - That Alfa axle looks slick.
Have any pictures with the disc brakes on the axle??
Ever get one of those Alfa axles on a scale??
