Prius II, 40 MPH safety
The Curt Class 1 receiver 1 1/4" hitch with 2"Euroball can save your car and perhaps your life. The design puts the ball level at optimum level to prevent torqueing frame bolt points. It can absorb an extraordinary amount of force/energy before compromising frame rails and even then reducing damage to vehicle survival repair costs. The Euroball performs like a shock absorber on steroids...imagine it being bent 90 degrees to form a "U" shape..be sure to use strong safety chains.
