Installation Notes and Tips

Ensure the vehicle is securely lifted and supported before removing the old shock. Verify that the upper stem and lower eye mount align correctly with the vehicle’s mounting points. Since the boot is not included, inspect the existing dust cover and replace if necessary to protect the shock absorber from debris.
