Detailed Description

This lateral arm is designed for the rear upper rearward suspension location on the Hyundai Genesis Coupe from 2010 through 2016. Dorman 528-228 uses stamped steel construction, a bent shape, and rubber bushings to match the original suspension layout and restore proper rear suspension geometry. The painted black, semi-gloss finish helps protect the arm while maintaining a clean OE-style appearance. This part cross-references Mevotech Supreme CMS901190 for the same application.

What It Helps Fix

• Rear suspension looseness or instability
• Clunking or knocking from worn bushings
• Uneven rear tire wear caused by worn suspension geometry
• Excessive play in the rear upper rearward arm
• Handling changes from a fatigued OE lateral arm

Installation Notes and Tips

Verify the rear upper rearward position before installation and compare the original arm length, mounting hole size, and bushing layout to confirm the correct replacement. Because this is a standard replacement lateral arm, alignment inspection is recommended after installation on the Hyundai Genesis Coupe. Confirm all suspension fasteners are torqued to the vehicle manufacturer’s specifications.
