The product does what it promises. Settled with a friend and day off. It's not an easy thing to install. I recommend taking it to become a pro. You have to compress the spring to rotate the damper. Those who say you don't need it don't realize the stress a spring goes through just from being twisted. Would I buy it again? no This is my first leveling kit and taught me how to spend a little more money on something better. Save money and choose another brand, e.g. B. a pre-built elevator that doesn't require you to use a spring compressor and is bolted into place. After installation you will need an alignment.
