    I have a 2007 UC and I am looking into order replacement clutch plates.
    According to the HD site there are 2 "kits":

    37969-03A (metal plates, fiber discs and spring)
    37980-10 (metal plates, fiber discs)

    If I am going to do this work, should I replace the sping or use the old one?
    My gut says replace it given that I would think heat would weaken the spring over time, but then I questioned why they would sell the spring seperately as well as with and without the plate/discs?

    Thanks for any advice.

    I do not think a primarys heat would cause the temper to go out of the spring...

    According to my chart, both part numbers have same list price of $169.95.
    I can't understand why that would be because it does not say 1 number was substituted?

    I figured it may be a typo on the website, but Zannotti's lists both part numbers as the same price ($142). I'll try contacting my local dealer and see what they say...

    Thanks for the reply Hoople!

    I agree with you, and given how simple the spring is (in design) I would think that there would not be a problem using a new one. Maybe it is my bad luck, but I have had problems installing something "new" and it was defective from the start. It always makes me think, if it is not broken and works, don't replace it. Then I end up out thinking myself!:p

    This weekend I am replacing the fuel filter and installing my new headers that came in yesterday from JetHot (originals cracked and I welded them). The clutch will be next weekend or later, but I am trying to get all the parts together well in advance.

    Thanks for the advice!

    Good to know. Thanks for the info, I don't think I want a heavier spring. I like my comfort and the original one worked fine.
