Help keep your front wheel properly located with the Dorman control arm 528-091, a front left lower arm designed as a direct replacement that fits and performs like the original equipment. It fits many vehicles, among them the 2016-2020 Lexus IS300, 2011-2020 Lexus IS350 and 2006-2015 Lexus IS250. See the Buyer's Guide tab for the full list and engine details.
This suspension control arm links the front wheel assembly to the chassis, holding the wheel in position while it moves up and down with the suspension. If a worn IS300 lower control arm is the cause of clunking, a loose steering feel or uneven tire wear, this part replaces it.
- Direct replacement: designed to fit and perform like the original equipment on the listed applications.
- Reliable fit: precision-engineered to match the design and dimensions of the original components.
- Durable construction: manufactured to strict standards from sturdy, safe materials.
- Rigorously tested: put through thorough quality-control checks aimed at longevity.
This listing covers the front left lower position. If the arm on the opposite side shows similar wear, consider replacing both at the same time. Consult the vehicle service information for torque values and whether the original fasteners may be reused.
