1. Here’s the Pro-Rigid link kit from Proven Wicked. The 12mm XM-style forged 4340 chromoly rod ends (with injection molded Teflon/Kevlar liners) used are not commercially available parts, but were instead custom-designed specifically for this application. The fronts are longer as to easily clear the strut flanges and are extra thick for increased stiffness. The rears are shorter to allow the use of two males with an adjustment collar for on-car changes in length.
