kws are nice. not as reliable as stock but what aftermarket product is. kw is constructed of aluminum parts and the springs are powder coated so durability is very good. if you decide to go kw i wouldonly adjust them to the middle setting and that is it. you will have to reprogram your instrument cluster to not recognize the air suspension anymore. I completed the process and it was tough but def doable with the help of a few on the board
