Overall impression: The item itself is high quality in my opinion. installation) and final results I found this elevator solution very valuable. For me (2018 F-150 Crew Cab with stock tires) the 2 inch lift up front actually left me about 1/4 inch tall on the nose. Installation and Wait Time: As others have mentioned, the instructions that come with it are terrible, but considering how many great videos there are of this installation (which are the same for all rack spacers), I didn't find the material issue that much. I'm not an auto mechanic. But I have been working with marine engines for many years. So I'm familiar with the tools and techniques, but definitely not with suspension components. Took me about 5 hours to install both. Most of the time was spent removing the B-bolts that attach the lower brace to the control arm (and my truck is only a year old). Important: Until you've adjusted the camber, you have no real idea of how your truck will perform once installed. When I first rode it I was a little annoyed by the reviews saying you keep the factory ride and handling. I even had a knock on the front end that bothered me. However, once I adjusted the camber these issues went away and the ride was actually the same as before the installation (despite the fact that the front end was taller). Also, don't forget to adjust the vertical alignment of the headlights (very easy) after installation!
