These dampers have really strengthened my rear triangle. They give more stability in corners. Even with 700-pound power tools in the back. You will need two jack stands to install them or the jack stands. After the old ones come loose, you'll need the power of the jack to squeeze them together. Unless you are the Hulk. You look great too. They add that off-road look that everyone is looking for. The only negative is that they can be heard. It is hard to explain. it is definitely an audible noise. Like a percussive spring sound. Not scary. But if it's on your luxury truck, I wouldn't take it. But for my upscale off-road baguette, they're fine. Oh, and just like all the others, this will lift your butt by about an inch and a half.
