UMI's 1" rear sway bar helps control body roll and improve handling balance on your Ford F-150. Most trucks come from the factory with no rear bar which makes the UMI 6580 even more important. Pair with UMI 6579 (2015-2020) or 6581 (2021-2025) front sway bar for the ultimate handling combination. Bolts in with no cutting or welding. All hardware included. 100% Made In USA
