I just didn't want to risk them failing. It might be overkill, but after talking to Lew at Alcan Springs, he said the four leaf springs are designed to break. Three inches out from the eye is the sheer point he explained. In looking at what we have and what he makes, it reassured me that we made the right decision. If the roads we travel never had potholes and we were always on great roads, then I might have chosen to not replace them.
