hey guys I exhausted the search button for this. I read through about 15 pages of search on leaf springs. From what I understand, sport trac springs are a direct bolt in and have a heavier load rating and provide a little lift since they are more arched. Also explorer springs? I believe they are a direct fit correct? and they will also give a slight lift? I ask because my dad just bought a 98 4x4 and we think the leaves are bad/ maybe broken. I tried to search for new springs but not much luck so if someone could provide a link to new ones for reasonable then please do. Would rather have new leafs but can just go to junkyard if no new springs are available for decent price. He wants a high rating to pull a little trailer. Thanks for all the help in advance.
