Roland Sands Design Clarity and Nostalgia Cam Covers are direct replacements for the stock units on your Harley-Davidson Twin-Cam or Milwaukee Eight motor. When the plain jane stock look of your motor just isn't doing it for you anymore our cam covers are an easy way to add some style to your motor. For those who yearn for the old style ribbed cam covers on the Flathead, Knucklehead and Panhead Motors our Nostalgia Cam Covers are designed specifically to give you that vintage look on your late model motor. For a more contemporary approach our Clarity Cam Covers were the first on the market to give you a window to your cam chest. Clear Lexan windows allow you to see the cam gears and chain working to keep your motor in time.
