7. Proven Wicked didn’t use guesswork and a magic wand to come up with their endlinks, they used science. Running finite element analysis (FEA) simulations you can see the difference between the OE links and the Pro-Rigid pieces. The ghosted gray image is the static non-loaded position; the red is the highest stress zones, and the blue signifies the lowest. Under high load, the stock endlink flexes, thus reducing the bar’s effective rate. Since the Pro-Rigid links are over seven-times stronger, they don’t flex, and the sway bar exerts its proper and consistent force. Also, this test was done with a stock bar. Larger aftermarket bars would cause the OE link to deform even sooner, and to a greater degree.
