I have run both the tuff country soft ride springs in the 2 1/2 lift and four inch. They both rode terrible in my 72 Shorty /forums/images/graemlins/truck.gif Well my 68 project is nearing the stage of ready to roll and I have reconsidered the current spring set as I want as smooth of a ride as possible and good flex without the harsh jolts. So I am considering trying some of the national springs. So does anybody have the specs on the stock front 3 leaf springs for a starting point in choosing a rate? I only want four inches lift, so they will not be able to have to many leafs in there. I am hoping for a 7 pack. Also, what would be a good spring rate for my truck as it tips the scale at 4800 pounds. Most of the weight is up front as I have no tailgate, and only a pre runner style rear bumper/tire carrier. Thanks.
