just like it says. i have a 10 bolt posi out of a 95 z28 that my friend wants to buy to put in his car but he is running about 550 hp and i dont know if this rear can handle that much power.

 

if the car is a 6spd..then it's only a matter of time...an auto might last 2 maybe three good hooking launches.

 

If you do a search you will see this discussed ad nauseum.

It will take as many 5500 RPM launches as it takes licks to get to the center of a tootsie pop.

and then BOOM.

 

550 hp .. wow! I would think your friend not only needs a 12 bolt but he would be looking at many other beefed up drivetrain components.

 

Yeah, 550 HP is a bit much for any 7 5/8 inch 10-bolt unless you are stick to street tires and do all the axle upgrades. Richmond gear says 400 RWHP is their comfortable limit on what to expect from a strengthened 10-bolt.
