Ideal for securely closing and protecting the spring ends on Gorilla lifts. Press for an easy fit and looks great, a great way to finish off the look. Although I don't understand why the gorilla lift doesn't include them if you're buying the lift system itself. And I have two sets, so if I lose or damage them I can replace them. It's worth it. I hate things that look unfinished. Being happy they are on me completes the look.
