Anyone seen or used one of these

That would be a great help in the instance of a broken main spring to help get you off the highway. It's a great idea but IMHO not very practical to carry around with you all of the time as a broken spring is less common than a flat tire.I also carry extra lug nuts lust in case. They dont take up much space.
