I've been trying and trying and for the life of me I cannot get dropshadows to work on tick labels. Am I missing something or is this functionality not yet available?

Hello Shane,

The LabelProperties element can’t be used directly to set visual effects for labels. It just set common label properties like location or font weight. To set visual effects or change label appearance you have to change label template. It can be done using ItemTemplate property of the LabelProperties object.
<Telerik:RadGauge x:Name="radGauge">
    <TelerikGauge:LinearGauge>
        <TelerikGauge:LinearScale x:Name="linearScale" Min="0" Max="100"

                <TelerikGauge:MinorTickProperties Length="0.055" />
            </TelerikGauge:LinearScale.MinorTick>
