H&R Sport Sway Bar Kit for 2012-2020 BMW 2, 3, and 4 Series - 28mm Front / 20mm Rear (72878-2)

Fits select 2012-2020 BMW 335i, 435i, 440i, M235i, and M240i models.

H&R Sport Sway Bars are engineered to improve handling and reduce body roll without compromising ride quality or requiring a lower ride height. By increasing the suspension's roll stiffness, these bars enhance cornering control, lateral stability, and overall grip. Each bar features smooth, precision-forged ends for maximum strength and consistent performance. This complete kit includes both front and rear bars, matched to provide neutral, predictable handling for your BMW chassis.

Constructed from high-tensile 50CrV4 spring steel, these sway bars provide a faster response time and smoother transitions during cornering. The kit includes H&R's proprietary sway bar bushings, which are manufactured from a special urethane/Teflon composite. This unique material eliminates the need for periodic lubrication and prevents the annoying squeaks often associated with aftermarket bushings.
