So I have these 4" TC ez ride lift springs from the front of my jimmy (from before the 57's up front swap) and I have this stock 86 chevy 1 ton. So i decide to put my 4" leaf springs underneath the 1 ton. 2 hours later I set her down on the springs and I deffinately dont get 4" out of it. How much difference is the spring rate between 1 tons and 1/2 tons. I think I got 2 or 2.5 " out of it (it is a new lift) but it is hard to tell with no bed.
