2011 PRO Multilink - S chassis - TENSION - TRACTION - TOE - CAMBER CNC Laser 5mm thick brackets, copper and gold plating make the new multilink a real work of art. All of these parts have a serious amount of thread overlap. All components like the sub frame reinforcing bearing side spacers are forged steel now instead of aluminum. With the forged clamping adjusters, combined with these other features, they are by far the strongest parts on the market today. They are also backed with a 4 year free pillowball replacement and lifetime manufacturers defect warranty.
