Due to the weak mounting system used for the rear swaybar from the factory, COBB offers a rear reinforcement bracket kit. This kit is designed to strengthen the rear sway bar mounting, and is a requirement when using the COBB rear swaybars. The rear reinforcement bracket kit is included in the COBB sway bar kits, or may be purchased separately for use with other aftermarket swaybars. Bolt on installation with no cutting/welding required, all hardware is included.
