COBB Tuning Adjustable Rear Antiswaybar Endlinks for the 2008+ STI are threaded to easily remove all preload from the bar and provides consistent handling balance in right and left turns. The construction of these endlinks start with carbon steel bearing rod ends utilizing a PTFE (Polytetrafluoroethylene) self lubricating corrosion resistant coating. The CAD designed and CNC machined spindles are 6061-T6 aluminum and hard anodized for a long lasting finish. Our endlinks were designed and assembled in-house for optimal strength, performance and durability. Adjustment is as easy as loosening the jamb nuts and turning the spindle to lengthen or shorten the endlink while installed on the car.
