This 24 1/2" inch Slipper Spring with 2 Leaves that is rated to 500 lbs per spring. This would bring a pair of these 24 1/2" inch Slipper Trailer Leaf Springs to 1000 pounds. These are common on 2000 lb trailer axles. The spring is 1 3/4 inch wide, and 24 1/2 inches from center bolt to the end of the flat leaf. If your springs measure slightly longer than 24 inches that is normal, springs can flatten out over time and measure slightly longer than they did when they were new. To get a more accurate measurement you will want to measure the distance between your hangers from center to center.
