Bilstein B6 Performance (DampTronic) dampers are a performance upgrade to OE dampers designed to be paired with OE factory springs. All of the active features of the factory electronic suspension, along with the factory controls, will be retained with the installation of these dampers. Each damper is rigorously tested for quality that meets or exceeds OE standards and features application specific valve settings with a monotube design to bring out the best handling performance of a vehicle. B6 Performance (DampTronic) dampers will deliver improved safety and handling performance in a package compatible with factory electronic damping control.\nTwintube Strut Assembly\nBMW 228i xDrive 2016-2015; 230i xDrive 2019-2017; 328d xDrive 2018-2014; 328i GT xDrive 2016-2014; 328i xDrive 2016-2013; 330i GT xDrive 2019-2017; 330i xDrive 2019-2017; 335i GT xDrive 2016-2014; 335i xDrive 2015-2013; 340i GT xDrive 2019-2017; 340i xDrive 2018-2016; 428i xDrive 2016-2014; 428i xDrive Gran Coupe 2016-2015; 430i xDrive 2019-2017; 430i xDrive Gran Coupe 2019-2017; 435i xDrive 2016-2014; 435i xDrive Gran Coupe 2016-2015; 440i xDrive 2019-2017; 440i xDrive Gran Coupe 2019-2017; ActiveHybrid 3 2014; M235i xDrive 2016-2015; M240i xDrive 2018-2017
