HSlider "thumbs" aren't getting close enough.

Question

Given the defined HSlider, I'd like the "thumbs" to get to be able to get as close as 50 units apart, however, they will only get as close as 300 units. The only solution I've found is to make the HSlide wider, does anyone have any better solution?

<mx:HSlider
    id="range" 
    thumbCount="2" 
    minimum="0" 
    maximum="8000"
    snapInterval="50" 
    tickInterval="500"
    labels="['1', '4,000', '8,000']"
    dataTipPrecision="1"
/>
