I've gone through two of them... I have no idea who makes them, but they pretty much all look exactly the same except for that smaller bar going across the center.
The brace is very nice until you bottom out of something... then it juts collapses. It's flat hollow tubing, so it's strong until something bends it. It makes a huge difference in chassis stiffness though.
Oh- it won't clear a 2.5 inch collector if you have one on your header.
