Auburn 9"

[Johnny Ray]

I am picking up my narrowed 9" Ford rearend this afternoon and currently I have a 2.73? open ring and pinion setup and 28 spline axles.

While I was there a few days ago a guy offered me a new Auburn 9" 3.50 Posi-Trac with 28 splines for $400.00.

He said he as had it for a while and ended up not using it on the project he just completed.

Is this a fair price?

P.S. I am not setting my car up for drag racing, just making a cruiser out of it and I do not beleive I will be getting enough power to the ground to worry about using 28 splined axles.

Thank guys!

:cool:

the 3.50 gear will help acceleration and the posi will help traction...but if you just building a cruiser and you dont want it to haul a$$ i wouldnt worry about it...

Yea, it is for the 460ci. Falcon with a C6 behind it.

The motor will only be around 375-400 horsepower as it is setup to be a low/midrange torque monster.

I am putting 12½" of rubber on the ground in the rear with street tires.

Im moving this over to drivetrain, I vote that the 3.50 will be better even fro cruising if you have an overdrive on that car of somekind - otherwise go 2.73.

well I gotta admit I don't know much about ford transmissions, but I gotta agree with Dom on this one, if you got overdrive I think the bigger axles with that 3.50 should be fine so long as you don't go with a really small tire, (which I am guessing you aren't if you are gonna put down 12 inch rumbber on it)

I personally don't see anything wrong with going with a little extra strength on stuff like that..

and even if you do go with a low profile tire on say a 15 inch rim unless you are doing alot of highway driving I think it will be fine..
