    The stock springs and ORD or Echo-bit shackle system.
    If you want a super flexy rear suspension - check out Marv Springer's "Springer suspension" with 57" Ford springs.

    4" shackle flip +rebuilt stock springs would be the best way to go. Stock springs are very flexy, if yours arent they are prolly just old/crusty. Take the whole spring pack apart, clean them up, repaint them, install new bushings and put UHMW-PE between the leaves and you'll be set.

    For the rear, the shackle flip/stock spring will probably flex better than most aftermarket lift springs. You could probably find, or maybe have custom built, lift springs in the rear that were real soft and would flex as good or better but the shackle flip is cheaper and easier.

    For the front, since the stock springs actually have an inverse arch the 4" lift springs are still relatively flat and therefore you really don't get any advantage to messing with the spring mounts like on the rear springs.

    In general you want to keep the springs with as little arch as possible because with all other things equal the lesser arch will flex better.

    Hmmm, custom link front end with King Coils...

    Custom built leaf packs from National, Deaver or Alcan...

    Air bags

    No suspension

    UHMW-PE = Ultra High Molecular Weight Poly-ethylene. Its basically an uber-plastic that is a) super tough b) slick and c) won't cold flow. You can buy it from plastics suppliers, check ur yellow pages. It comes in 3" wide strips and for spring purposes 0.030-0.060" thick is best to use. I have a sheet of it between each leaf in my spring packs, full length, not just at the ends. No binding in my springs! /forums/images/graemlins/grin.gif The stuff is easy to cut with good scissors (especially the 0.030 stuff) so cutting it down to fit on 2.5" wide springs is no big deal.

    yeah, UHMWPE is good stuff. I'd recommend it to anyone that has old crusty springs or springs that seem to bind a lot. I woulda put it on my front springs too if they didnt have the annoying folded-over type of clamps on them. They are Rancho HDs, so its prolly a lost cause, but it would prolly help a lil! /forums/images/graemlins/smile.gif
