X2.... OME struts are not longer. I personally measured them.
As for the squeaking, did the rubber sleeves on yours slide down to the bottom of the tube? These sleeves prevent the helper spring from rubbing against the tube which makes noise. I glued mine in place.
Would an extended length strut be beneficial with the lift?
