What posi and axles is everyone using?

I can't seem to find any axles or posi set ups for the 8inch

 

I have the powertrax fully streetable locker it is for the ford 8 and 9 in. open with 28 spline axles.

 

The axles are the same as the one-legger rear-ends.

I think Auburn Gear makes a Traction-Lok unit for the 8-inch...

 

I had a lock-rite locker in the 8 inch with the stock axles before changing to the 9 inch with a spool and 35 spline Moser axles.

 

There is plenty out there for the stock axles. I was leaning toward powertrax, but got cheap and went with a mini spool for $40, or maybe $60. I don't recommend that, save up the $350 and put in a "limited slip" locker.

 

Thanks guys

How many splines is the stock axle? And is it worth upgrading if I'm just doing a mild build of a 302? Or will the stock axles be fine?

 

Stock axles work fine,seen several 8"s in 11-12 sec cars with no more than gears/spool.

 

Alright cool Saves me some money.. So I guess all I need is a limited slip and a set of 4.10s now

 

Actually I was just doing some calculating and it may seem like 4.10s would be too much. I need everyones opinion.. It would be like a 25in-26in tall tire with a c-4. With 4.10s it would spin at around 3,400rpms, seems a bit much

 

I would suggest something in the 3.90 range, it's a good street strip, stoplight to stoplight gear. The 28 spline axles (stock) are the same as the 9 inch 28 spline axles. Fine for a car that is mostly street. Save for some sort of posi or locker and the gears will make the most noticable change. Good luck!

 

^ Yeah thats the next big thing I'm getting

I have 3.73s in my mustang so I wanted something bigger so maybe I'll try 3.93 or something

 

You don't have as many choices with an 8 inch vs 9 inch

Typical ratios on new gears
3.00, 3.25, 3.40, 3.55, 3.80, 4.11, 4.62

 

3.80 it is then

 

If you are using a stock to mild cam, a set of 3.55 gears would be the ideal for the street. If you are going to use an AOD or a 5-speed, you can get away with 3.90 and lower gears. An AOD with a 4.11 gear would have a final drive ratio of around 2.85. That's having your quick performance and gas mileage, too.

 

Its going to be a c-4 for the time being. So.. I'll look around at my options, I guess it'll be between a 3.55 or 3.80
