    Rear springs are 100% better than blocks. With springs, you don't get any axle wrap. Blocks are better moneywise. Alot cheaper than springs. If you get a lift of 6" or greater, it's usually springs for the rear instead of blocks.

    Axle Wrap is when your axle tries twisting when it's under a load..like whe your pulling a FORD out of a hole. It's almost like your whole rear end turns with the axle due to high blocks. As far as springs breaking, I'm not real familiar with that situation but the way I look at it, if a spring is gonna break, it's gonna break regardless of what you have for a lift. Maybe someone else can elaborate.

    " More arch causes spring to break easier"?
    I had stock springs with a block and bent both springs, my friend has 6" spring on his burban and has no problem with them. Spring steel is made to hold it's shape so it wouldn't matter if it was a 4" spring or a 12" spring it is made to hold it's shape. Blocks cause axel wrap which will after time cause spring failure because you are stressing the spring in the wrong point. So springs are better then blocks, but a flip is better then both.IMO

    Only benefit I can think of besides cost that blocks have over springs is that blocks lift the spring up higher out of harms way. This could prevent damage to the spring.
