This is a high-quality gas spring from FEBI BILSTEIN, designed specifically for the tailgate of your vehicle. Part number 01787 ensures a precise fit and reliable performance. Gas springs are essential components that assist in lifting and holding open the tailgate. They are filled with compressed gas and oil to provide controlled movement, preventing sudden drops and making loading and unloading easier and safer. Over time, these springs can lose pressure, leading to a tailgate that is difficult to lift or does not stay open. Replacing worn-out gas springs with a new FEBI BILSTEIN unit will restore the original functionality of your tailgate. This ensures convenience and safety during everyday use, whether you are accessing your boot for groceries, luggage, or other items.
