ACU,
There is a 99-05 body style ford up my way with a hot 12v cummins in it, and even tho it had a ton of power, it would bounce until it broke or the driver let out everytime it pulled. A few months later talked to the guys who built it and asked them if they fixed it and they pointed out the full length traction bars they added to the front axle. Said it cured all the bouncing they had.
they made a center cross member and had both the front and rear traction bars mounted at nearly the same place, and the last time I saw it pull it did very well, put a bit of distance on the rest of the field that night.
