what is the difference between all spring and a add a leaf?
aal sux in short get the full packs as for the difference the add a leafs is only one spring that bolts in between the old packs and will sag normally within a few months from what everyone say mine started to sag within 3 months and full packs is a brand new set of leaf springs so they will hold up better in the long run try searching around on here you will find that there are alot of lift kit reveiw type threads on here good luck
