Front Left Tension Strut, BMW - G20 M340i, G22 M440i

This part is listed by BMW as BMW part number 31106879849 (31 10 6 879 849) and is described as the left thrust arm for G20 M340i and G22 M440i. This is the complete thrust arm, also known as a pull rod, tension strut, or upper control arm.

Worn original rubber bushings cause steering vibration, imprecise steering feel, and sloppy handling. The bushings are replaceable on their own but a complete arm is the better option as it also includes the outer ball joint. The arm also comes fully assembled which greatly simplifies installation.

This is a Genuine BMW Thrust Arm with a two year warranty. Buying a Genuine part will usually be more expensive than an OEM or aftermarket brand but you are assured that it meets BMW's designs for fitment, performance, and longevity. It will also be the very latest design, incorporating any updates or revisions that an aftermarket brand typically will ignore.
