Bought these for my 2020 Ender 3 Pro. Very easy to install and only took four so I have a spare. They are much better and stiffer than standard springs and definitely keep the bed level better than standard springs. I've since added an automatic bed leveling sensor so this isn't an issue anyway, but I'm hoping these springs will keep my bed pretty close to what I set the bed to the last time I manually leveled it and the limits of my ABL have not tested .
