The shocks are at best ok. Now heavy duty at all. As a matter of fact, they can't hold the weight of the car. I attempted to add air and it was forced out due to the weight of the car itself. I'll be buying some real shocks that's made for a Lincoln.
Buying experience was perfect. As far as the shocks go, i purchased them for my Lincoln for when my handicap scooter was on back. They wouldn't even make car level. Car sat perfect with a set of gas shocks but squatted so low it was unmanageable on road with air shocks. Gas shocks are back in.
