Mevotech Supreme Suspension Control Arm P/N:CMS901235
Keep your Audi's rear suspension located and aligned with the Mevotech Supreme control arm CMS70164, a rear left upper control arm that links the wheel knuckle to the chassis, guides suspension travel, and helps hold wheel alignment. Engineered in-house with application-specific upgrades, it's a direct-fit replacement across a wide range of Audi and Porsche applications — including the 2012-2018 Audi A6, so swapping in a fresh Audi A6 control arm is straightforward.
Built for high-usage commercial and passenger vehicles, SUVs, fleets and working trucks, this Mevotech Supreme suspension control arm is a solid choice when the original wears out. If a worn control arm or ball joint is behind clunking over bumps, wandering steering, or uneven tire wear, replacing it can help restore proper wheel location — have the suspension diagnosed to confirm the cause.
Fits many Audi models — including the 2009-2016 A4, 2008-2018 A5 Quattro, 2012-2018 A6, 2010-2019 A8 Quattro, 2009-2017 Q5, 2009-2016 S4 and 2008-2017 S5 — plus the 2015-2025 Porsche Macan. See the Buyer's Guide tab for the full list of applications.
