2. The front suspension of our truck was previously set up to lay frame over a set of 17s. This meant that a pocket in the frame was already cut for 2,600-pound airbags with mounting cups. Also, 2-inch drop spindles were already in place, and the shocks were relocated to the side of the arms. Even though the previous setup worked for our old 17s, it needed a lot of new fabrication work with our new wheels. To start, the lower control arms were removed, after the tie rods, sway bar, and spindle were unbolted.
