The highest capacity 1-3/4" wide slipper spring we offer is 3,700 lbs part # SP-040275 which measures 30" long end to end. If you need a higher capacity then you will need to upgrade the hangers and equalizers to accept 2" with a kit like the Tandem-Axle Trailer Hanger Kit for 2" Slipper Springs part # APT6SE so you can use the 6-Leaf Slipper Spring w/ Hook End for 8,000-lb part # e46SR.
