No ford 9 inch, what do you recomend

You might need to provide more information about this rolling chassis mate. Eg, is it from a kit manufacturer or home made, any provisions for diff/suspension mounting points, etc.

I think that the good old B/W ford diff is plenty, Its what I have in mine, 28 spline, 4 pinion LSD, 3.73 diff ratio.
yeh I had it shortend to suit my application, cost me $100 for the 2nd hand diff (complete) EA falcon Disc. To shorten with new 28 spline axles, all brackets welded to suit custom suspention, tailshaft made & balanced all for $1800 total!!!

You can have it all done and fitted to your chassis for under 2k !!!

Some people put a hell of alot of street HP through these diff's without any problems. Another person I know has an un-cut B/W in his cobra, but the rim selection was not able to have any dish, I like the deep dished type rims, thats why I had mine shortened.

Hope this is of use to you.....

Here's a thought,
That 9 " can handle 900 hp +or- depending on build, also you can change the ring and pinion in the time it takes to take a healthy **** and won't break the bank, plus a high school dropout can work on them.
If you get into some of those exotic rear ends you have to be a Rhodes Scholar to work on them, not to metion special tools and a pocket book that would let you shop at BJ's auction.
Think About It!
