Keep the front right upper forward corner of your Audi suspension precisely located with the Mevotech Supreme control arm CMS701149. This control arm and ball joint assembly installs as a direct-fit replacement across a wide range of Audi models, including the 2017-2020 Audi A4, the 2017-2025 Audi A4 Quattro, the 2017-2025 Audi A4 Allroad, the 2018-2019 and 2021-2023 Audi RS5, and the 2017-2025 Audi S4.
The control arm positions the wheel and links it to the chassis, while the integrated ball joint lets the suspension travel and the wheel steer. Worn arms and ball joints can bring on clunking, uneven tire wear, or imprecise steering — if the original arm or ball joint is the cause, this assembly replaces both at once.
It also fits the Audi A5 Quattro, A5 Sportback, S5, S5 Sportback and RS5 Sportback — see the Buyer's Guide tab for the full list of years and models.

Which corner does this arm mount on?
