Limited Slip
This is more of an educational post than anyhting else, do any of you rear end guru's actually know what limited slip does?
My truck is equipped with it, and I know several of my friends have it in their trucks. When I really get on my truck on dry pavement I have the "one tire fire" and if I goose it off road, same old story. If I am very careful on the throttle I can rip two nice ruts in a lawn, but that is the only evidence I have that the limited slip is different than an open rear end. For those of us who do not know, could someone please enlighten us?

The proper name would be "unlimited slip" as they essentially do nothing. They send the power to the wheel with the least resistance. So if you have one tire in mud, and one on pavement, you're not going anywhere because the one in the mud will be the one spinning. The only "real" cure is a Detroit.

While the LS diffs on our trucks seem to be only marginally better then open diffs,,,,lately since I have put on my " Winter set of studded tires" the new added traction over the Contis seems to help the LS unit work more,,instead of just spinning and then 1 wheel slipping,,,both rears seems to be sharing the load now,,I think because of the much better traction.
Just yesterday I had my 16' 4-ton Equip. trailer on, my back yard has about 1" of snow on it,,and is slightly up hill (enough to go sliding on sleds in the past yrs) and the truck (06' F-350 6.0) pulled the trailer up and around and then backed it up the hill to park the trailer,,,all in 2-wheel drive !! The Contis never would of done that !
Very impressed with the studded Hankook RT03 MT 285/70/17's,,glad I went with them,,so far !
