This is the OEM front left tension strut for the F10 528i/535i/550i, F06 640i/650i GranCoupe, and F12/F13 640i/650i (non-xDrive) models. The tension strut is also known as the thrust arm and is the forward-most control arm on the F10/F06/F12/F13 chassis. The arm includes the outer ball joint and inner hydrobearing bushing. The bushing is filled with a vibration-absorbing fluid that does a great job of isolating bumps and rough roads, until the fluid leaks or evaporates. Worn F10/F06/F12/F13 bushings will affect the ride, handling, and steering of the car and can also cause clunking noises and vibrations. A new bushing is only available with the complete tension strut arm (not sold separately). To restore steering precision and taught handling, replace the complete tension strut at the first sign of wear.
This is an OEM thrust arm manufactured by an original supplier to BMW for this part, as well as many other arms and bushings. As the OEM it meets all of BMW's original design, fitment, and performance requirements and is TUV approved. OEM parts are the best alternative to more expensive Original BMW parts because they are virtually identical without the inflated price tag. This part has a two year warranty.
Powerflex urethane replacement bushings are also available (see below).
