Anyone who has ever taken apart a fork knows how much of a hassle it can be, both to unscrew things and even worse to put it back together. With this spring tool you can press the spring down and insert a wedge that holds the spring in place while you unscrew the top cap. It is often a problem to get to the lock nut that needs to be loosened to remove the piston rod at the top. If you are doing suspension and especially upside down forks, this kit is a must-have.
