What It Helps Fix

• Suspension noise during braking or cornering
• Loss of rear suspension alignment control

Installation Notes

Install on the exact listed positions only: rear lower forward or rear lower rearward. Verify vehicle year, model, and suspension location before replacement. Because this arm is not adjustable, final alignment should be checked after installation to confirm suspension geometry is within specification. The package contents include the lateral link only.
