These urethane performance bushings replace the stock rubber front upper control arm bushings on the 2006-2010 E60 525xi/528xi/530xi/535xi xDrive AWD models. Stock rubber control arm bushings give a disconnected and mushy feel to the front suspension, especially when worn as the bushing deflects more than it should. You get sloppy steering, vibrations, and poor handling which makes the car feel unstable. These urethane bushings are stiffer than stock rubber and will not deflect as much. This helps keep the alignment in check with less variation. The car feels more planted and confidence-inspiring. And a limited lifetime warranty means you'll likely never have to pay for another bushing ever again (applies to Street bushings only, see warranty page for complete info).
Sold as a pair for the front upper control arms, also known as tension struts or thrust arms (see diagram). Replaces BMW part numbers 31126768302 in the BMW 31106770685 and 31106770686 control arms.
