I've used small tusk spring compressors and they might be fine on a quad but they're pretty much useless on a UTV. The tusk clips were not compressed enough to be usable, they slipped and scratched the feathers. These clamps have a much larger area to clamp the spring harder. And fix firmly without moving. I spent 1.5 hours with tusks trying to figure out how it works. It took 15 minutes to meet.
