Hi every one I am new here and I have an 04 qc 2wd with a 4.7. the truck has a 3.55 open rear
end and I am looking to change the gears and add a limited slip but cant seem to find one any where! Any one got any ideas or do I have to swap the whole rear end for a 3.92 with limited slip?

 

dont the trucks already have a limited slip? I'd rather have a posi rear

 

Limited slip and posi-traction are the same thing.

 

I have found Posi units but they are all for 4x4 and the carrier is different, Any one got any info or done this before?

 

So I take it no one one this website has any ideas or info on this?

 

Actually, I beleive that posi is constant power to both back wheels, where as limited slip doesnt kick in until the wheel spins.
