I have a couple of question for you guys. I know I will be getting 4.10 but should I get the eaton posi even though I will be sticking with the 28-spline? Should I save even more money and get the 4.10, eaton posi, and 31-spline? I am not tryin to produce more than 320 to 350 to the wheels.

 

Definately consider the Detroit True Trac for your differential... Cant get better than that...
Edit: Oh and its limited slip not a posi... no clutches to burn....

 

I would say don't change the posi unless you are going to go up to 31spline, just doesn't seem worth it to me.

 

So I should use the same posi as what I have in there now or get an eaton posi?

 

If you got the money... It's time to upgrade.

 

Would it benfit anything if I do get the eaton posi? When would I have to rebuild the posi?

 

My car has 87,000 hard miles on it and when I got my 4:10's in 2,000 miles ago they said that I should look into a rebuild within the next year. If you have the cash then upgrade for sure but you can get buy for a little bit w/o a rebuild...
