I felt uncomfortable using hard spacers with my EZABL- Setup because the frame pretty clearly doesn't support my bed straight/square and I knew this would lead to a mile static level I decided to use these compression springs to safely level my bed and after 30 hours Pressure it's still dead They're a lot stiffer than the originals and great solutions for a 'rigid' bed installation with some adjustment to accommodate 'assembly tolerances' Springs in stock.
