JD said:You can actually make it four-wheel with judicious use of left-foot braking.
Because diffs are lazy (from an engineering perspective) it will put most of
the torque to the wheel that is slipping. Applying a bit of brake will force
it to balance the torque better. While, it won't work as well as fully
locking diffs, it is pretty effective at getting you unstuck.
I've been left-foot braking for years, it actually bugs one of the guys
at work when I'm driving the "land barge" up to a mountain radio site in
deep snow. Land barge = F550 Ford 4x4 crewcab with 8'bed.
Land Rover and Jaguar "do it for you" in their traction control systems,
and I'm certain that automated braking is at least part of the new
stability control systems that have come out recently.
My first experience with left-foot braking was drag racing 35 years ago.
I had an auto trans Chevelle with a fairly lumpy cam. It actually
launched better if I kept the brakes on lightly when leaving the tree.
The trick was learning to get off the brakes as quick as possible once
the tires hooked up well.
