What It Helps Address

Installation Notes and Tips

Install in the rear upper forward position only. Verify vehicle year, make, model, and suspension configuration before ordering. Because this arm is non-adjustable, final alignment should be checked after installation to confirm rear suspension geometry is within specification. Use the included mounting hardware during replacement.
