I have previously replaced an air spring with an OEM part and paid close to $300 for that part alone. I found this on Amazon for 1/3 of it. It seems just as well done, maybe even eliminating a major design flaw in the OEM. One thing to be careful about is that it wasn't exactly the same size as the part it replaced. It's actually 2 inches taller than the one on the other side of the car. However, with the air in the bags, it immediately evens out and you don't even know it.
