Well, almost. Interesting concept. I can't tell if it actually uses the bolts in the wheels or not, but it does seem to appear that way.

Those are sweet, I couldn't help but notice they were testing it with a Dodge! just think how much better they will work on a Ford or GM truck!!

Duck I can feel the $hit coming.

They are pretty cool.

Here they are using a GMC: http://www.youtube.com/watch?v=XwpKjEa4LYY

Very interesting! Everything is driven completely from the exiting tire surface. They do have an assembly that bolts to the lugs that allows a turnbuckle to be attached (and rotate freely) as a way to secure the unit to the truck, they use a chain in the inside to secure it to the frame.
