Abstract: An apparatus and method of articulating a vehicle is disclosed using a rotatable shackle connected to the frame and the suspension system of the vehicle. As one side of an axle is moved to a different levels from the other side, the shackle rotates, allowing the vehicle to articulate and assisting the spring eye of a leaf spring suspension system to remain substantially in its resting position. Pivoting connections may be provided where the rotatable shackle is connected to the frame, where the rotatable shackle is connected to the suspension system, and within the rotatable shackle itself. The rotatable shackle is self supporting and may include a bushing to receive a portion of the rotatable shackle.
