Thanks for the hook up Kolak! These OME units are 15.25" collapsed & 25.5" extended. My stockers measured at 15.0" collapsed & 24.25" extended, with all measurement taken between the center of the bolt holes. That translates to an extra 1.25" of shock drop in the rear, trackbar/swaybar permitting. But I'm sure the ride has to be better than my played out OEMs. Time to trail test!
