What It Helps Address

• Rear suspension looseness or worn control arm bushings
• Improper rear camber settings on covered Honda and Acura models
• Clunking or shifting from worn rear upper suspension components
• Uneven tire wear related to rear alignment issues
• Restoration of rear suspension control after component wear

Installation Notes and Tips

Verify vehicle fitment by year, make, model, and rear upper position before installation. Because the arm is adjustable, final alignment should be checked and set after installation to confirm camber is within the specified range. The part includes bushings, but does not include a grease fitting or ball joint.
