This strap attaches to a brake caliper mount and then over the triple tree, and then back to the other caliper bolt on the other side. You then "pull" the stap to the desired height and let go. It basically works just like a motorcycle tie down does, and has a release button to press to put the bike back to the stock height when riding on the street. This strap is intended for off road use only, not for use on public streets or highways. Always observe safety first. These straps are approved by NHRA and Prostar for the Street ET and Pro ET classes.
