Dorman CB91343RD Rugged Duty Suspension Control Arm and Ball Joint Assembly

The Dorman CB91343RD is a Rugged Duty (RD) suspension control arm and ball joint assembly engineered specifically for severe-duty service applications. Built for vehicles that demand more than standard replacement parts, this assembly is ideal for off-road work, heavy hauling, towing, and other demanding operating conditions.

Key Features:

• Rugged Duty construction — ball joint housings are crafted from quenched and tempered steel rather than standard normalized steel for superior strength and longevity
• Exclusive protective coating on both the ball joint housing and included hardware for enhanced corrosion resistance
• Pre-loaded with premium grease in specially designed grease boots to ensure proper lubrication retention and streamline installation
• Hardware included — all necessary fasteners ship with the assembly, coated for corrosion resistance
• Direct OE replacement — designed to restore smooth ride quality, directional stability, and predictable handling dynamics
• Ideal for emergency and public safety vehicles such as ambulances and off-road rescue trucks requiring maximum dependability

The Dorman RD line represents a no-compromise approach to suspension repair, delivering a stronger, longer-lasting solution for hardworking vehicles that standard-duty parts simply can't match.
