I went thru a lot of sites trying to find what I'm talking about and these are as close as I came:http://www.pirate4x4.com/forum/showthread.php?t=955735. What they are is just what it sounds like. You have those main frame rails just doubled with tube spacers ever 6-12 inches apart. From what I have found its called a 25-1 chassis and it greatly reduces flex in the frame. Most of the frame kits I found added another 2K dollars over the price of their normal full tube chassis and the guys running them were 10.5 tire guys and up with serious horsepower. But if your driving it only at the track without that much planned hp I suppose you don't it.
