1,750 lb each (3,500 axle), 3 leaf, 21.5 inch (center to center of holes). I bought new at Napa in Evanston due to an emergency, replaced them, and drove 80 miles home. Once I got home I replaced everything, including all springs with 4-leaf springs, so these wouldn't have matched. These are $47.50 each at State Trailer (which is where the Evanston Napa purchased them from). Price is for the set.
