Built for vehicles that work hard, the Dorman control arm CB81237RD is a front left upper control arm with ball joint from Dorman's RD line, engineered specifically for severe-duty service. It fits many vehicles, among them the 2006-2023 Dodge Charger, 2005-2023 Chrysler 300 and 2008-2023 Dodge Challenger, as a direct-fit replacement for the listed applications. See the "Vehicles it fits" section for the full list.
The RD on the packaging stands for 'rugged duty.' This control arm and ball joint assembly is aimed at vehicles used for off-road work, heavy hauling and towing, as well as emergency vehicles such as ambulances and off-road rescue trucks. It links the wheel end to the chassis, and its ball joint provides the pivot for suspension travel and steering.
- Upgraded direct replacement: Designed to fit like the OE design in the specified severe-duty applications, and engineered for improved durability.
- Tougher ball joint housing: Made of quenched and tempered steel rather than simple normalized steel, then finished with an exclusive protective coating. This combination is designed for added durability and corrosion resistance.
- Hardware included: The necessary hardware comes with the arm and also carries a corrosion-resistant coating.
- Pre-greased where applicable: Where applicable, each joint is pre-loaded with premium grease inside specially designed grease boots with molded-in standoffs. This is intended to streamline installation and help keep lubrication where it belongs.
If you are replacing a damaged or failed 2005-2023 Chrysler 300 control arm on a vehicle that can't afford downtime, the RD line is built for that kind of duty. Dorman's chassis engineering and manufacturing experts in the United States stand behind it, along with more than a century of automotive experience.
