How many of you that have installed the rear superduty springs in you're trucks have used the superduty overloads as well? I'm planning on using them, as they look the same as my stock f-250 overloads. I plan on hauling a camper eventually and my boat. I like to be able to haul loads and use the weight capacity of the truck. Do they line up with the stops? and how do they work? Thank You.
