Keep your Lexus's front end tight and its steering responsive with the Mevotech Supreme Suspension Ball Joint MK500114 — an IS300 ball joint that drops in as a direct-fit replacement across a wide range of Lexus IS and GS models. This front upper ball joint forms the pivoting connection between the control arm and steering knuckle, letting the suspension travel and the wheel steer while carrying road loads.
Engineered in-house with application-specific upgrades for high-usage passenger vehicles, SUVs, fleets and working trucks, this suspension ball joint pairs premium materials with Mevotech's Labor Saver™ hardware for a faster install.
- A faster fit: ships with the part-specific nylon locking nut to speed installation.
- Resists corrosion: a protective surface treatment helps guard against rust build-up and supports longer part life.
- Keeps water and debris out: a pre-installed rubber dust boot shields the internal components from contaminants.
- Rigorously tested: extensive in-house and third-party durability testing back its strength.
Fits front upper positions on the 2006-2015 Lexus IS250, 2016-2022 Lexus IS300, 2011-2022 Lexus IS350, 2006 Lexus GS300, 2007-2011 Lexus GS350, 2006-2007 Lexus GS430, 2007-2011 Lexus GS450H and 2008-2011 Lexus GS460. See the Buyer's Guide tab for engine-level details and the full application list.
