The Barnes 4WD Pro Series GM Dana 60 Front Axle Truss is a full width low profile truss made from a combination of 1/4 and 3/16 Ultra 100 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!
