These things are awesome! I am on my third Ford super duty, and drive around 70,000 miles a year, about 1/3 loaded and 2/3 empty. Are usually take them to around 350,000 miles before trading them in. On every one of the vehicles, I have experienced substantial vibration through the steering wheel on the highway. On two of the three super duties, I have experienced the dreaded Ford death wobble, including my current F350. I installed these on my 2017 F350 in about a half an hour total. The difference in drive feel is incredible. I went from substantial vibration coming through to the steering wheel to almost no vibration coming through the steering wheel. I drove 400 miles the day after I put them on, on a road that I drive frequently. I know where I have lost some control before, and with these installed I could barely feel the bumps. There is no question in my mind that I will never drive a super duty again without these installed. They should come standard on every super duty manufactured.

They Springs really stabilized the front of the vehicle. They were super easy to install and the installation instructions were right on the money.

I instantly felt the improvement as I pulled out of the driveway.
