Help bring precise, quiet handling back to the front suspension with the Mevotech Supreme control arm CMS301114, a front right upper control arm and ball joint assembly that drops in as a direct-fit replacement for the listed applications.

This part cross-references / interchanges with the following part numbers:
Is this a 2014-2024 Infiniti Q50 control arm?
Yes. It's a front right upper assembly listed for the 2014-2024 Infiniti Q50, along with the 2009-2020 Nissan 370Z and 2014-2022 Infiniti Q60. See the Buyer's Guide tab for the full list.
Does the ball joint come with the arm?
Yes. The control arm and its ball joint come as one pre-assembled unit, so you replace both the arm and the integrated ball joint together.
What material is it made of?
It uses cast aluminum construction built to OE-level tolerances, with an additional surface treatment that helps resist rust build-up on the ball joint.
What are signs this upper control arm may need replacing?
Clunking over the front suspension on acceleration or turns, loose or wandering steering, and uneven tire wear can signal a worn arm or ball joint. Diagnose the cause before replacing.
Do I need to replace both sides?
Suspension parts often wear at a similar rate, so inspect the opposite side and replace it too if worn for balanced handling. This listing is for one assembly.
