Detailed Description

For drivers searching for a rear suspension arm for 2011-2016 Kia Optima or a rear upper rearward arm for 2011-2015 Hyundai Sonata, GS901070 offers a fitment-specific solution.

What It Helps Address

• Rear suspension looseness or instability
• Clunking or knocking from worn arm bushings or ball joint wear
• Uneven rear tire wear related to suspension geometry issues
• Excessive rear-end movement over bumps and road joints
• Loss of OE-style handling response in the rear suspension

Installation Notes and Tips

Install GS901070 on the rear upper rearward position only for the listed Hyundai Sonata and Kia Optima applications. Verify the existing suspension layout, fastener condition, and alignment requirements before installation. Because this assembly is not adjustable, final alignment should be checked after replacement to confirm rear suspension geometry is within specification.
