Not as much as a Land Rover Discovery (11 inches) but it will do. Due to the very good A-Trac system both airborn wheels did not spin at all and I idled across with traction on the left front and right rear - No sweat!
I have to agree the atrac works great. Otherwise we would be stuck there with 2 wheels spinning without a locker. Atrac is awesome (other than all the noise it makes).
