• Noise or looseness from aging loop-mount shock hardware interfaces
• Loss of ride consistency in rear suspension service replacement

Installation Notes and Tips

• Verify rear fitment by year, make, model, and package before ordering.
• Confirm the loop upper and loop lower mount style matches the vehicle.
• Check compressed and extended length against the original shock before installation.
• Inspect surrounding suspension bushings and mounting points during replacement.
• Use the listed rear application only; do not substitute for front suspension use.
