Limited Slip???
Is there any way to put a posi-trac in the rear end of these superduty trucks? My limited slip is not so limited any more, all it does is slip. I need all of the input possible. Thanks!!

You could get a better LS unit, perhaps an Auburn, or if you really want all input possible, go with a spool or locker, but neither are recomended for street driving.
You could go with a air locker, very nice, but pricey.

Give us some particulars on your ls what yr ,how many miles?
Have you changed the fluid with the correct friction modifier
get it rebuilt from a good shop or do it yourself
to put new clucth packs in, is not that hard
Just my 02
as yeti! stated aftermarket lockers are pricey for what you use the truck for. street driving
Just my opinion

Like FortyFords said- unless you were unhappy with the performance of the LS when new, your most economical choice is to have the factory LS rebuilt.

I read that replacing the existing diff fluid with Amsoil can fix it. I'll let you know if it works or not, i'll be doing an oil change soon!
