Built for trucks and vans that tow, haul and work off-road, this Dorman control arm, part number CB90497RD, connects the front suspension to the steering knuckle through its ball joint and comes from Dorman's severe-duty RD line. It fits many vehicles, among them the 1999-2000 Chevrolet Silverado 2500, 2003-2025 Chevrolet Express 2500 and 2003-2025 Chevrolet Express 3500, and installs in the front left upper position. See the Buyer's Guide tab for the full list and engine details.
The RD on the packaging stands for "rugged duty," Dorman's line of chassis components engineered for off-road work, heavy hauling, towing and other grueling conditions. It also suits emergency vehicles that demand dependability, such as ambulances and off-road rescue trucks. As a Dorman suspension control arm and ball joint assembly, it is intended to replace damaged or failed original equipment on specified vehicles.
- Upgraded direct replacement: designed to fit like the OE design on specified severe-duty applications, and engineered for improved durability.
- Quenched and tempered steel housing: the ball joint housing uses quenched and tempered steel instead of simple normalized steel, and is finished with an exclusive protective coating 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: joints are pre-loaded with premium grease in specially designed grease boots with molded-in standoffs, which streamlines installation and helps keep lubrication where it belongs.
Dorman backs the RD line with a team of chassis engineering and manufacturing experts in the United States and more than a century of automotive experience. Consider replacing the left and right arms together.
Signs a control arm or its ball joint may need replacing include clunking over bumps, loose or wandering steering, uneven tire wear and a torn ball joint boot. Diagnose the cause first, and follow the vehicle service information for installation and torque specifications.
