    got my springs tonite, but confused. no directions. surely somebody out there probably knows.

    the military wraps go to the fixed end??? or the shackle end??

    which pair go on the front, the 7 leaf or 8 leaf. I think I specified 200 over stock both ends.

    thank you for any help

    military wrap to fixed end. spring count should match oem counts, which is normally more springs in front, but with custom aftermarket springs, that is out the window. match the springs lengthwise with what you have on the rig.

    I would assume the 8 leaf are the front as the fronts are supporting a lot more weight because of the engine.

    thanks for advice. old springs are under a foot of ice snow mix and I'm not even sure I labeled them.

    What shocks are you going to run? Care to provide the part numbers for future reference?

    don't know about shocks yet, bilsteins?I understand from dieselhead there are 2 stiffnesses???

    I work kind of slow, just sandblasted frame, hope to have chassis, drivetrain done by end of summer and start body... to finish next winter

    kurt has my diffs, maybe rolling chassis by end of march.

    55 rear springs are longer. :cool:

    I'd run the Bilstein 5125's which are available in 10,12,14" lengths... 255/70 valving is the kind you want.

    7 leaf front, 8 rear. The rear leafs have more leaves because it has to carry all that metal and glass in the ass-end, not to mention the other crap pig owners add.

    One thing I don't like about Alcan is that they build their Cruiser leaves with the same amount of springs as the OE packs. Weight carrying capacity is dependent upon the thickness of the spring (IIRC, anywhere from 6-8mm). They do this as to not affect the spring geometry (so I was told), but it takes away from the tune-ability of the packs. Get it right on though and the springs work really well.
