Sold as a pair. The factory sway bar links casue horrible binding and strange loading on the sway bar. These are a direct replacemnt and easily bolt right on. We use domestic 3-pc teflon rod ends and cromoly sleeves  as well as new 10.9 hardware. These are adjustable as you can bring the sway bar "up" a bit for more clearance on trial set-ups. Sway bars will often "twist" over time and these can also be used to compensate for the preload if need be, or to make the sway bar "neutral" at ride height. These are shown in red but standard plating is BLACK.
