I am on an ANTI VORTEX movement. I recently bought a couple of their products and they were GARBAGE. My buddies have bought their sprockets and other items. They wear quickly, or warp and bend out of the proper shape, other items have broken OR come in a condition that will not work with OE hardware like most people would expect as well as NOT COME WITH ANY HARDWARE AT ALL. Beware of Vortex products and thier POOR quality and workmanship. I personally refuse to buy their stuff anymore. I'm sure that there are plenty of higher quality products to purchase out there.
