I see a lot of the Toyota crowd running Ironman Foam Cells with good results. I have a complete Nitrogas kit for my GX470 that I had listed in the Classifieds as I was going to sell the GX and get a 3rd Gen Tacoma. Now I've changed my mind and will likely wind up with a GX460 that I'll install the Nitrogas kit on. Any opinions on these? The GX will be used on mild trails here in the PNW, on max 265/70s or 275/70s. I figure if I've already got the setup, why not use it?
