which is better to build an 86 9 bolt or a 90 10 bolt

and what about a 96 10 bolt would that fit under a 90 iroc?

guys at my shop

 

Which has more parts and gear ratios to choose from, for less money? 10-bolt.

Which will last longer after you get it together? 9-bolt.

 

like five7 said a lot depends on how you define best

 

well he wants it to last and he's got cash and a built motor which is stonger?

 

12-bolt from Currie.

If he's got cash, nothing else makes any sense (unless it's a 9-inch from Moser - but then it's not GM).

 

well i is a 9 bolt and its a gm thing from AUS thats all i know :lala:

 

Check out www.9bolt.com He sales parts for them and he has a link to an Hot Rod Mag Article talking about the strength of a 9 bolt.

I think 4th gens were different widths. I'm not for sure though. Just concluded that since the backspacing on the rims are different. I'm sure if you did a search you could find info. I've read something about that on here somewhere.

 

I have broke them both :-)


now i have a 9" moser

 

the 96 axle will fit under the car and blot right in but in order for the wheels to clear properly you need to use 4th gen wheels because the 4th gen axle is wider than the 3rd

 

....dam wide a$$ed 4th gens... couldnt just keep it simple.

 

As said above, its really a toss-up. You could fork out the massive amounts of money on a 9-bolt or you could build and break 2 or 3 different 10-bolts and still be even (money wise). Even then both will probably break eventually. Wanna do it right might as well fork out the cash for an aftermarket 9" or 12bolt

Whoever told you that was wrong. Yes they are wider (1" I believe?) but that will not cause any problems with your wheels.

 

Just to be clear:

A 9-bolt is the GM Ausie rear.

A 9-inch is a popular high-strength Ford rear. They are available from Moser for 3rd gen F-bodies.

 

well i dont mean to feed the fire but im asuming alot of the people using this board have a larger size tire than normal and or have a lowered suspension so all these things combined with putting your wheels out 1/2 inch or more than there suppossed to be could just maby result in a few clearence issues but i dunno i could be the fool

 

Adding to what fire... had to say about 9bolt.com, Miles has a 427 feeding in to his 9 bolt. I guess the 9 bolt isn't as strong as a Dana 44, but it will still take quite a bit of abuse.
