Dorman CB90054RD Rugged Duty Suspension Control Arm and Ball Joint Assembly

The Dorman CB90054RD is a severe-duty suspension control arm and ball joint assembly built for vehicles that demand more than standard replacement parts can offer. Part of Dorman's exclusive RD (Rugged Duty) chassis line, this assembly is engineered specifically for applications involving off-road work, heavy hauling, towing, and other high-stress operating conditions.

Key Features:

• Severe-Duty Construction: Ball joint housings are manufactured from quenched and tempered steel — a higher-grade material than the normalized steel used in standard replacements — for superior strength and longevity.
• Corrosion-Resistant Finish: An exclusive protective coating is applied to the housing and all included hardware, helping to resist rust and degradation in harsh environments.
• Pre-Loaded with Premium Grease: Where applicable, joints are pre-loaded with high-quality grease and sealed in specially designed grease boots to retain lubrication and streamline installation.
• Hardware Included: All necessary mounting hardware is included, also featuring a corrosion-resistant coating for long-term durability.
• Direct OE Replacement: Designed to match the fit and function of the original equipment, restoring smooth ride quality, directional stability, and predictable handling dynamics.
• Ideal for Emergency and Commercial Vehicles: Built to meet the demands of ambulances, off-road rescue trucks, and other vehicles where maximum reliability is non-negotiable.

The Dorman CB90054RD is designed and manufactured to strict specifications, backed by Dorman's team of chassis engineering experts with over a century of automotive experience. Whether you're replacing a worn control arm on a work truck, fleet vehicle, or emergency responder, this rugged-duty assembly delivers the dependability the job demands.
