Steeda Mustang Adjustable Competition Rear Sway Bar (2015-2026)

Once you add stiff springs, aero and adjustable shocks to a track Mustang, the factory rear bar is often too stiff. The car lifts the inside rear tire on corner exit and loses drive. Steeda's adjustable Competition rear sway bar is intentionally softer, so the rear stays planted and puts the power down out of the corner.

Developed on track

Steeda found that with stiffer competition springs like its Dual Rate Springs (555-8243/555-8244), a softer rear bar was needed for the best corner exit grip. This bar is up to 39% softer than Steeda's standard rear bar (555-1016).

Three settings

Compared with the base GT factory rear bar, hole 1 is 23.6% softer, hole 2 is 7.8% softer and hole 3 is 13.1% stiffer. Relocation brackets and hardware are included.

Highlights

• Better corner exit grip
• Three adjustment positions
• Includes relocation brackets and hardware
• Ideal for open track and autocross
• Pairs with the 555-1015 front bar
• About a 1-hour install

Note: Designed for track builds with stiffer springs. On a stock-suspension street car, a standard Steeda rear bar is usually a better fit.

Fitment: 2015-2026 Mustang GT, EcoBoost, Mach 1, Bullitt, GT350, GT500 and Dark Horse. Steeda part #555-1034.
