the stock differential on my 1985 iroc z cannot handle the awsome power that my car is making so i would like to know if anyone knows of a place i can get a rear end that will hold 600 horsepower ,the car originally had 215 h.p and it just cannot be pushed with the 7.5 rear thats on it.

 

Put in a Ford 9". That's one of the only things Ford did right!!! And strong performance parts are abundant.

 

The awsome power of 600hp?????

 

 

built right, the Ford 9" will take well more than 600hp. my uncle runs a Ford 9" in his Vette, he's putting just under 1500rwhp out of that beast (TT 502 BBC)
