This is an old set of 4 inch Genuine Suspension Ball Joint Extenders. They came off a '55 Chevy. What these do is give the car 4" of travel/lift off the line and they allow the weight to transfer to the back of the car. These will not lift the front of the car or give you a higher stance, but big block springs will give you stance height in the front. These go in between the upper A arm ball joint and the top hole on the spindle. These worked very well in my car, giving it 4" of travel/lift off the line. Free Priority Shipping in the U.S.
