    56\" springs versus 57\" springs

    Has anybody tried both of these setups? I like the idea of additional flex and twist from the longer springs. I have a set of 56" springs already. All I hear about is 57" ford springs. What about 56"ers. In the future I will be ordering a six inch kit with 2" and ord flip for the rear probably zero rates on both ends. For a total of 7" of lift. If the 56"ers are flexy enough I would rather stay with them. Anybody have an educated opinion on this? /forums/images/graemlins/smirk.gif

    Theoretically, 57 is longer than 56 so you get more flex, enough to warant buying the 57 if you have the 56? no.
    Now the 57's are very soft but if you remove one from the 56's you will also have soft.
    If you want to step up, go with the 63" GM rears 88 and up I believe? /forums/images/graemlins/thumb.gif

    The 57's use thinner leafs which is why they'll outflex the 56's even with the same number of leafs...

    I know that Rene.
    That is why I said remove leaves, you could experiment with the number.
    Personnaly I have the 56" leaves and I will be doing some testing.
    Eventually I am getting the 63" springs. And maybe put the 56" in the front. /forums/images/graemlins/thumb.gif

    I'd say run what you got, but for sure the 57's are softer. I have both 56" and 57" springs sitting side by side on my floor and my "foot spring compression dyno" says the 57's are way softer. /forums/images/graemlins/thumb.gif

    Those 57's are hours of springy enjoyment for the kids too! I imagine they could easily make an effective oversized crossbow with the right fabrication equipment and heavy mounting surface.
