K/D super servo's

Has anyone used the Shift Technologies K/D front band super servo's. They are claiming 11% more holding capicity and firmer shifts just by using their front servo's. I was thinking of getting one and pairing it with a Transgo TF-SC kit. What are your thoughts? Just trying to firm up the shifts some on a near stock rebuild.

If you're just putting in the small SK kit, don't bother with the servo. I've sold them in the past, but they went either in a high performance or HD diesel application. I'm not saying that it's a bad thing, just that on a near stock rebuild, it's not needed.
