    hey guys. I have my rear springs all apart right now anyway, and I was wondering what I should use between the leaves. My packs have the factory teflon thing between the bottom 2 leaves...but not much else.

    One of my local 4x4 buddies said I should put some UHMW (ultra high molecular weight or something) plastic in there. Supposedly better than teflon for this app. Any ideas? What do you guys use, and do you have a little sheet of this stuff between each leaf or just the bottom ones. Whatever u use, where do you get it?

    Help appreciated! As soon as I get the 1" zero rates from ORD (thanks for the speedy shipment SW!) on monday, the springs are going back on...want'em to be as good-to-go as possible. ;)

    I bought the plastic buttons from a local spring shop that builds the springs for many US brands (including James Duff cant recall the huge list the guy spielled off)
    $0.30 each

    Off-Road magazine did an article on this awhile back. I think either UHMW or Teflon would be good. They put a thin "sheet" between each leaf( the same dimensions as the leaf) if I remember correctly. Look in the yellow pages or the web for Plastic suppliers.

    &gt;the same dimensions as the leaf

    wait a sec...the *same* dimension as the leaf? ie, length-wise too? I thought all that was needed was a piece maybe 6" long, that would be centered on the spring packs center pin. If not, lemme know! Wanna get it right the 1st time. =)

    OK, I found the article.....this is what they did....
    1) Deburr all the ruff edges on each leaf with a grider or file.
    2) Coat each spring with epoxy paint.
    3) Place a "liner" the full length and width between each leaf.
    It seems that most of the friction occurs at the ends of the leafs....that's why you find manufactures using the plastic "buttons" at the ends. A full length just seems like it would be even better....
    They never said which plastic to use, but it looked like they went with UHMW. They said between .030-.060 thick material. They got it from www.jmartin.net/parker/goose.htm

    michael...awesome!!! Thanks much man. that helps a lot! The other thing thats cool, is that I already did the de-rusting phase...and the only paint I had left to use on them just happened to be some epoxy-based stuff. =) Looks like I stumbled into doing the right thing once again! ;)

    Jason, there are a couple of places in Portland that sell HMW in various forms, sheet/rod, etc. Check the yellow pages. I just can't remember the names but one is down by Portland State.

    Teflon isn't the right stuff to use for that application. Telfon cold flows, that is, it will actually spread itself out thinner and thinner when under pressure. I think you would pretty quickly be replacing it with something more durable.

    It lets the springs flex better and gives you a smoother ride.

    UHMV is the stuff to get...just don't grease it. The grease will attract all sorts of debris and the debris will get embedded in the UMHV.

    Any ideas on where to get it? Can it only be had at specialty plastic suppliers or...?

    I've used plenty of it through my work, but I've never had to buy it or source it...sorry.

    Teflon's real good. I have had a lot of luck adding some Lithium-based White Lube during the assembly, and that keeps them quiet for about 1 year (or until winter's damage).

    I found some lithium white lube in a spray bottle, and I can jack up each wheel and spray in a bit of that, and they're good to go again.

    Also, every water crossing washes the lube clean, so it's spray time again.

    The stuff also works on sqeaking steering wheels, door hinges, and not-K5 related but sliding glass doors too.

    By the way, using dry graphite lube is good, it won't attract dirt. Grease of any kind will.

    Most of the UHMV stuff we get is round stock or thick slabs...but I'm sure any thickness would be available. I'll ask where they get it from when I return to work on the 2nd of Jan. [​IMG]
