Do I need a PosiTrak rear

My 2005 Screw has the non-limited slip diff. I have a roush supercharger installed. Is the non slip diff a bad combo.

If you want to do one wheel tire burners.

Or what I call... peg legged burnouts...

Right now I have the 3:73 non limited slip. Where can I order limited slip and will any shop install it or just a speed shop?

I would think that any shop should be able to do this, the stealership would be able to but would prob charge you out the rear.. Try a local garage, just make sure that they have experiance in this type of service. From what i hear it is very specific and easy to screw up.

Lately I have been only doing one wheel peels, how can I tell for sure if my LS has gone out. Its been raining a bunch (in AZ i know the last 2 weeks doubled what we've had for the year) and I like messing around and it will only peel one wheel around corners when I want to spin both and kick the rear around. I have RP in the diff, could it have to much ls additive? My LS just doesnt seem to be hooking up like it used to, it used to be scary driving in rain it would break both loose all the time and slide the rear around, and just punching it I think only one is breaking loose.

Sounds like the clutch pack is bad in the LS. I suggest getting a better LS, like an Eaton.

As far as a place to buy one, look on the internet.

I like these people: http://www.drivetrain.com/eatonposi.html

The only time it's a problem is when you lose traction. Since you're running a Supercrew, I'm sure you have troubles lighting up the tires even with the Roushcharger.

Are you able to break them loose or do you get decent traction?
