Paolo, I am far from being an expert on this...but if the adjustment was this high on the threads and you were also using a 1" spacer, if you want to keep the same ride height I suggest getting a longer QA1 shock and spring...I am guessing the shock was operated beyond its designed ride height. Going to a longer spring and shock may be the solution for you.. https://www.jegs.com/p/QA1/QA1...ocks/743895/10002/-1
