Motoracer I'm in the same boat as you right now. Alcan are about my only opinion because you can tell them what your looking for in your spring and how much your truck weighs and etc. See my probably is I'm building my truck for hunting mainly but I want to be able to still go crawling. So I had to weight my flatbed with my dog box on there and I even weigh the dogs so I can get an a close idea how much weight. And after talking to the guys over alcan a bunch of times its really the only way to go cause you can get just about what your wanting.
