Put them on the back of a 12 year old Yukon 4x4 with 65,000 on it. I did it at the same time with quick release struts in the front (different brand due to availability). One of the originals at the rear is completely gone, greatly improving the ride quality. Installation was pretty easy and would have been a lot easier if it was on a lift, but that's not a problem. Used them for about 2 months and would buy them again. Definitely recommend doing all four turns if you drive originals with this mileage. It just enhances the whole journey.
