My old "Catalog 90" shows the 716 to have a KY=800 lbs/in and a recommended load range from 5600 lbs to 10800 lbs with 8000 lbs at center scale. This spring has a total deflection range of 8 1/2" but the catlog recommended range is 6 1/2". This spring will handle deflections from 2" to 3" and be within 25% load variablity.
Good Luck,
