Restore factory suspension geometry with this often overlooked part -- Priced each and sold individually **Direct replacement, fits front left and front right applications** This link connects the left and right sides of the suspension via the sway bar. This component is a notorious, but often overlooked wear item and helps provide stability to the vehicle while cornering. After years and thousands of miles, the ball joints deteriorate and can no longer provide the resistance needed to create the spring effect the way the bar generates under cornering. If your E46 feels sloppy and has slow responses in the corner this small piece could be the culprit. We recommend that this component be replaced in pairs for the best service life and performance.
