Installation Notes

Verify rear fitment by year, model, and standard suspension configuration before installation. Confirm the upper stem and lower eye mounting style matches the vehicle’s original shock absorber, and inspect surrounding suspension components for wear before replacing the damper. Professional installation and a post-installation alignment check are recommended when suspension components are serviced.
