ttb stands for twin traction beam. it's fords independant front axle found on post 79 ford 1/2 and 3/4 ton trucks and broncos as well as rangers and bronco 2's. It is basically two axle housing halfs that pivot and scissor past each other as the suspension travels. They can be easily swapped out for a solid axle;)
