what is the approx. spring rate of a RF 3/4 ton truck spring? NCA *SAYS* they will enforce the 'stock suspension' rule, so I'm just gonna use a truck spring next year. If they don't enforce it...I'm puttin racin springs back in. lol

My book shows anywhere from 800 to 1090 pounds. Another site with a spring rate calculator is http://www.proshocks.com/calcs/coilsprate.html
