Bought this spring compressor as it was recommended on a forum for my particular vehicle when replacing the rear springs. The vehicle itself is an SUV with independent rear suspension so the springs are rather beefy. When this thing arrived, I was surprised at the weight of the box. It was heavy. Inside, the spring compressor was packaged nicely in its own case. Upon using it, wow. Definitely a hell of a lot beefier than those little threaded rod type compressors that car guys know as 'widow makers.' The perches that go against the spring actually have a slot they fit into, and then bolt in. Also, when using this thing, turning it takes little to no effort which makes me feel safe as those widow makers seem to require crazy amounts of torque and feel like they'll let go of the springs. All-in-all, this thing was a champion. So far I've only used it on one project, but I think whenever I do suspension work again, this will be my go-to. My widow makers have found their way to the back of one of my garage shelves, and this tool will be my primary method of compressing springs from here on out!
