You can pull 16 inches of travel on a TTB. It will need long radius arms. The cut and turn is moving the lower balljoint out typically or pie cutting the beam. How much you move the balljoint out is determined by the height you are going to run. Most run 5.5 Deaver coils (JBG has them), but you can run any 4 to 6 inch coil. To get 16 you will have to clearance the center joint. Plenty of folks run 35s with a TTB, but it will crush a stock heater box on full stuff. You can go to Autofab's website and see his 16 inch setup. The TTB will give you a very fast front end, superb for desert racing or the dunes. Camburg and Spirit make beams and there are plenty of small fabricators around. Beams usually start at around $300 and go up. The TTB is a very very good front axle.
This is my first post btw, hello all.
