I have the zero rate on the 6 inch bds springs already, but I am considering moving the axel forward and wondering if it is worth it. I have a body lift and currently dont hit the cab. Also I have my cross over here, and my main concern is that the zero rate will affect my cross over set up? are my concerns valid? what would ya do? also this means I would have to raise the rear /forums/images/graemlins/frown.gif but I just had my 57 inch springs delivered /forums/images/graemlins/deal.gif and I assume my rear will be lower now? I currently have a echo bit shackle flip and 2 inch sky jacker springs back there /forums/images/graemlins/1zhelp.gif I may wait untill I have a better sollution or if I find some 63's /forums/images/graemlins/thinking.gif also located some 52's for the front..again "last set turned out to be 56 inch spings" /forums/images/graemlins/angryfire.gif but that is another story and I'm done with it. ebay is overrated /forums/images/graemlins/rolleyes.gif Just getting tired of messing around with springs all the time, not to mention multiple centering pins I keep replacing. Any one else go through them alot?
