The stamped steel arm provides structural strength, while the rubber bushings help isolate road vibration. This part cross-references Dorman OE Solutions 521-667 for the same application.

Common Problems This Part Can Address

• Excessive front-end looseness or wandering
• Clunking or knocking from the lower suspension area
• Worn ball joint or deteriorated bushings

Installation Notes

Verify vehicle year, model, and front left lower position before installation. The 2003-2006 Hyundai Tiburon application is for vehicles without stabilizer bar mounting tabs. Because this assembly includes bushings and a pre-greased ball joint, it is suited for a direct suspension service on the listed Kia Spectra, Kia Spectra5, and Hyundai Tiburon applications. Part number RK620520 should be matched to the exact fitment shown for the vehicle.
