I have the 2T aluminum Harbor Freight racing jack. It will lift the front high enough without a block but in the back I need a block of wood if I don't use the diff.

Careful of which direction the grain is when using wood; I've had a 4x4x4 cube *explode* lifting a truck before; Make sure the grain crosses the long axis of the lifting point.
