get the puddymod

 

Use the stocker and don't dump the clutch. If you break it go with the puddy. For what it's worth I put a year and 10k miles on my stock diff at 450.

 

i have about a year and a half, 20k+ miles, couple tire spinning trips to drag strip, 10-15 burnouts on the street, on my stock diff

i've only popped a driver's side axle once

 

Agreed, the diff will last if you don't hammer it to hard. I have 570whp and no issues at all. Just depends on how you drive...maybe I am pussy and just don't launch and roll into it who knows.

 

IP R200 diff kit lol but might be out of your budget range

 

i think i might fab together an 8.8 rear while my stock stays on the car so when it breaks ill have the swap

 

The factory diff holds fine with that, relatively, low amount of power. What DFWs2k said is a common story, I ran mine at 600 rear wheel on the favtory diff and only blew a driver side axle with no other problems. Although, a diff such as a ford 9" can be fabricated at a lower price than any of these diff kits, its just not the easiest thing.
