Firm up your front suspension and steering with the Mevotech Supreme control arm and ball joint assembly (CMS10108), a direct-fit replacement for the front left lower (rearward) position on the 2008-2013 BMW 128i and 135i, 2006-2007 323i, 2006 325i, 2007-2013 328i and 335i, 2006-2007 330i, 2009-2011 335d, 2011-2013 335is, and 2010-2015 BMW X1. See the Buyer's Guide tab for the full list of applications.
Mevotech Supreme parts are engineered in-house with application-specific upgrades, and these control arms are built for high-usage commercial and passenger vehicles, SUVs, fleets and working trucks. The arm locates the wheel while its integrated ball joint and rubber bushing let the suspension travel and keep steering geometry in check. If worn bushings or a failing ball joint are behind clunking over bumps, loose or wandering steering, or uneven tire wear, this Mevotech Supreme lower control arm replaces those components in a single unit — a popular BMW X1 lower arm as well as a fit for the 1 and 3 Series listed above.
Will this fit my BMW X1?
Yes — CMS10108 is cataloged for the 2010-2015 BMW X1 along with several 1 and 3 Series models. It's a common BMW X1 control arm replacement; check the Buyer's Guide tab to confirm your exact year.
What position does the CMS10108 cover?
It's the front left lower rearward control arm with an integrated ball joint. Replacing it addresses that one corner of the front suspension.
Is a locking nut included?
Yes — a part-specific locking nut is provided to speed up ball joint installation as part of Mevotech's Labor Saver design.
What is this control arm made of?
Forged aluminum construction, with additional surface treatment on the ball joint that helps prevent rust build-up for longer service life.
Do I need to replace both sides?
This listing covers one front left lower rearward assembly. Replacing the matching side at the same time is good practice for balanced handling, but it isn't required.
