my car is pushing out enough hp's now that i need to start worrying about blowing out the rear end. i have no idea when it comes to axles on what size or how many splines and what not that i would need. would anyone be able to help me out with what i would be looking for for my 04 gt? I'm eventually looking to put out a lot of power with this car and want to change these axles once. any help would be great.

 

You'll need 31 spline axles and a 31 spline differential. Below are links to what you need basically

wow thats def expensive for that posi. is that the best application? cause if im gonna spend that much on a rear i want to only change it once. ya know

 

also how much hp will those axles be able to handle before they snap? thanks

 

I can't tell you an exact number but you're not going to break them. Trust me unless you plan on pushing INSANE power that thing is practically indestructable

 

awesome. def the answer i was looking for. i appreciate your help. i am completely lost in this topic. now i just gotta break open the piggy bank. lol

 

You could also look for a 31 spline 8.8 Ford truck differential (100 bucks or so) and have it cleaned up. Then you could get your 31 spline axles. It'll save you a good chunk of change. Several of our locals here do that and they're still holding up after 100's of 5-6k launches on d/r's and slicks alike.

 

What kind of power levels are you making, and what tires are you running? So long as you run nothing more sticky than a nitto d/r you should have no problems with the stock 8.8

 

i got 400 hps right now and i run mickey thompson drag radials on it. but i wsa talkin to this one guy and he was saying that i should prob look at getting a 9 in rear

 

alot of big boys step up to the 9.0, might want to look into that - but thats only if your hardcore
