Can someone clear this up for me please. I've noticed that instead of getting taller springs some get longer shackles and a drop front hanger. Why would you want to do this over just getting taller springs. Are flatter springs better for ride quality or flexibilty.
Thanks


All things being equal, a long flat spring will flex more than a highly arched spring. The more arch a spring has the stiffer it is. My front springs only give me about an inch of lift, if that. The rest (3") comes from the lowered front hanger and longer shackles:
