which one is stonger, i've been told that 9 bolt is stronger, but i have not yet seen anyone use it for their performance upgrade....btw:

9 bolt - 3rd gen
10 bolt - 4th gen

 

9 bolt - 3rd Gen
10 bolt - 3rd/4th Gen

9-bolt =

I know a guy who has been running his 9-bolt behind his 500hp/tq BBC for 5 years and no problems. I'll be putting in a 9-bolt as soon as I find one! Good luck!

9 bolt that's for damn sure. http://www.9bolt.com/ I wouldn't trust a 10 bolt under a power wheels car.

I was interested in also, but I thought they were to short for the 4th gen cars. mine is a 95

 

They aren't a bolt-in....it would have to be widened.

that link says the ring and pinion is only a 7.75" ring gear and ours is only a 7.5. I thought the small ring gear was our biggest weakness.

 

9-bolt is stronger. They are a bolt-in for some of us
