Product Description

The H&R 71426 Sport Rear Sway Bar is a performance suspension upgrade engineered for the 2005-2010 BMW M5 E60 and 2005-2011 BMW M6 E63 with the S85 5.0L V10. Featuring a 21mm diameter and three adjustment positions, this rear anti-roll bar increases roll stiffness and helps reduce unwanted body movement during cornering. The adjustable design allows the rear suspension response to be tuned to the driver's preferred handling balance.

Designed to install in the factory rear sway bar location, the H&R 71426 maintains the vehicle's original ride height while improving lateral stability, cornering control, and turn-in response. The bar uses the factory rear end links and is supplied with H&R urethane/Teflon composite mounting bushings. It is suited to performance street driving and handling-focused builds where improved chassis control is desired without installing lowering springs or changing suspension height.
