    What posi?

    I had a friend tell me to go with one from a z71 since it's limited slip but what do yall think I should go with.
    I'm planning on installing 4:10 gears but I want a posi also and wanna knock out both at the same time

    Tru Trac

    It is a limited slip not a posi but is much better than the factory G80 that I had. I changed mine to a Tru Trac when I did my gear swap.

    I have a factory g80 and 3.73 gears for sale cheap if that's what you're looking for.


    I just put in a true trac. It's nice for racing/offroading...but definitely takes some adjustments ON the street. Tends to kick out a lot more then it used to.
    blown transmissions are about as useful as 97% of the guys on this forum

    you have a posi in there or a LSD

    to the OP yeah the tru track is a great way to go and can handle some abuse. Mine hasn't missed a lick and i got it from Rons a site sponsor.
