I didn't feel comfortable using hard braces with my EZABL setup because the frame that supports my bed is obviously not straight/square and I knew it would drop the static level by a mile would. I decided to use these springs to safely level my bed and after 30 hours of typing it's still working. They are much more rigid than the originals and are a great solution to the 'rigid' installation of your bed with some adjustment to allow for 'assembly tolerances'. I also recommend them for people with manual alignment adjustments, they still have a wide range of adjustment and work much better than stock springs.
