Crafted from solid heat-treated chromoly (CrMo) steel, this rear sway bar features a three-position adjustable design, allowing you to fine-tune handling balance for your exact driving needs—whether that’s daily driving, towing, or performance use.
Installation is simple and straightforward—requiring no cutting or welding—with all brackets, end links, and mounting hardware included. For maximum performance, pair the rear sway bar with UMI’s matching front sway bar (6579 for 2015-2020 F-150, or 6581 for 2021-2025 F-150) to achieve flat cornering and race-proven handling.
Like every UMI Performance part, the 6580 rear sway bar is 100% Made in the USA and tested extensively for real-world and track-proven durability.
