I just picked up my dana 60 and 14 bolt for the plow truck (300 for both /forums/images/graemlins/grin.gif) Im building this summer, and i want a set of 2.5 inch lift springs to keep the nose from bottoming out and high centering me on snow drifts. Who makes good and stiff 2.5 inch springs that will survive the weight of the plow. I was thinking rough country or trailmaster myself. Anyone have any suggestions???
