Stiffer sway bar bushings (also commonly referred to as anti roll bar bushings) reduce play and deflection in the sway bar. Rubber bushings tend to get soft and pliable over time and allow the sway bar to flex too much. Stiffer bushings restore stability and performance. All Powerflex bushings come with a lifetime warranty.Check size to confirm before ordering.
