Equal-length I-beams are the rage in two-wheel-drive setups, but in order to execute them properly, the steering needs to also be modified. The most popular solution is known as a double-swing-set steering system. On this truck, the factory power-steering box moves a modified pitman arm that's attached to an idler arm on the driver-side of the frame. This idler arm swings two steering links. One of the links steers the passenger-side tire, while the other link steers a second idler arm mounted on the passenger-side of the frame. Connected to this arm is a third steering link that steers the driver-side tire. In almost all cases, the links need to be bent to avoid hitting the framerails during full suspension compression.
