Technical specifications

Installation requirements

As an electrically connected suspension component, this damper should be installed by a qualified technician. Disconnect the battery, release the damper harness carefully and keep the plug clean. After installation, clear suspension fault codes with a diagnostic tool, verify the system is operating normally and complete a wheel alignment. Replace dampers in pairs for balanced handling.

A failing magnetic damper may cause a service suspension warning, uneven ride quality between sides, knocking over bumps or visible leakage. Diagnosing the fault with a scan tool first helps confirm which corner needs replacing, saving unnecessary parts cost.

Fitment checks before ordering

Fitment years in the listing are inconsistent, and left-hand-drive North American and Chinese market vehicles may differ from others. Please match the part number on your existing damper or provide your VIN before ordering.
