6\" lift questions I currently have 4" TC EZ ride springs in the front of my truck. Before I removed the 400 sbc they were starting to sag and "w" pretty bad and that was with no bumper. I almost have my 454 built and also built a winch bumper which will weigh abaout 100 lbs to go on the truck and I know it will finish off those springs. I like the TC brand suspension and was curious if the 6" springs have a stiffer spring rate to hold the extra weight of the BBC and extra front end weight. I don't wanna have to replace the springs again in a year because of them sagging like I am now. Also would a stiffer or double shock setup help too without loosing articulation? Thanks.
