Hey guys. I was just wondering if Gears from 2000 Camaro will fit 87 Iroc Z. I dont know whats the rear end in Iroc thats why I am asking. Thanks a lot !

 

Yes it's a 7.625" or 7 5/8", but is still sometimes refered to as a 7 1/2" rear...I have a Zexel Torsion Posi same as a late model Z.
Have you checked the ratios to see what you already have, see the numbers stamped on the ring gear as 42:13, divide the two and you get 3.23's...

 

No, it depends. The 87 IROC can have a 9-bolt rear end, or a 10-bolt rear end like the 2000 Camaro. What engine is in the IROC? That will help. If its a 350 engine, then you definitely have the 9-bolt rear end.

 

It will also depend on what series carrier you have and what the 00 Camaro has.
3.08 and numerically lower gears are 2 series carriers and 3.23 and numerically higher are 3 series.

 

The gear from the 00` Camaro is 3.23 ratio. The engine in Iroc is a 350.

 

The then the IROC gears will need to be 3.23 or higher number as said, or you'll need a ring gear spacer. And yeah, I was assuming you meant they were both 10 bolts', ID'ed by the number of bolts in the rear cover. I'd find some 3.73 GM's out of an S10....

 

does anybody know about a ford 9 bolt made for our cars id like to buy one either that or rebuild my rear bullet proof i have a 10 bolt 7.5 they only one which came in the 305tpi
