I noticed in problemchild's signature he's got Bilstein Silver shocks. Does anyone know the difference between these and the regular Bilstein yellow shocks?

The yellow Bilsteins are for stock height and the silver are for lifted trucks. I've got the Bilstein silver 5100's in front. Some use the yellow ones and then use spacers if the bars are cranked.

I have the silver ones in the front only cuz I cranked up my TBars to level the truck out and needed the extended ones

Many thanks.
