what 6\" springs? I am going to order new springs and was wanting some opinions on what would work best. I know everybody says TC EZ rides but my truck has a BBC, Th400, 205, large steel front bumper, and heavy steel nerf bars. Will the EZs hold up to that kind of weight or should I go with something more stiff like the HDs. I wont be doing much extreme flexing but do want the ride to be as good as possible while having springs that wont wear out fast.
