The Barnes 4WD Pro Series Ford Front Dana 60 78-79 Truss is a full width low profile truss made from a combination of 1/4" and 3/16" steel to keep it light but incredibly strong. These trusses reach all the way to the steering knuckles and are designed to give you eight inches of separation from center of the axle to the center of the upper link mount. They are made in the USA from USA steel!
