The standoffs were a little less than 2 inches tall but added about 2 1/2 inches to the front of my 2015 Lariat F150 4X4. You need to find an installer who knows how to install them. The first place I tried to use wasn't very familiar with the installation and they wasted their time and mine installing it. The second place I used got the job done in a few hours and had no problems.
