depends alot on how you apply the power and what you do to strengthen the rear. as far as being bullet proof it never will be if you abuse it.

 

Hey there is a guy trying to unload a Ford 9" that would bolt into your car and handle all of the abuse you could throw at it. He has posted on this site. Wait a minute that guy is me. I want $750 for the housing and axles. You would use your brakes and buy a third member from E-Bay for $475 Them you are bulletproof.
