COBB Tuning Adjustable Rear Anti-swaybar Endlinks for the GT-R 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 starts 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 jam nuts and turning the spindle to lengthen or shorten the endlink while installed on the car.
