Front Left Wishbone, M Sport - G42 230i/M240i, G20 330i/M340i, G22/G26 430i/M440i

This part is listed by BMW as BMW part number 31106888855 (31 10 6 888 855) and is described as the Left Wishbone for M240i (G42), M340i (G20), and M440i (G22) models. It's also used in all G42 230i and G22 430i models. And is the wishbone for the G20 330i with the optional M Sport package. This is the M Sport control arm - tuned for a slightly firmer ride and sportier handling.

The wishbone (aka lower control arm) is key to the great driving characteristics of your BMW. The inner bushing naturally wears prematurely and the outer ball joint will also wear and develop play. When either becomes too worn it will ruin the driving experience and possibly cause a suspension failure. We always recommend checking both inner and outer bushings along with the upper control arm (thrust arm) when diagnosing issues.

This is a Genuine BMW Left Wishbone 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.
