Boots ripped and ripped within a month so I have to oil them after a month. It should be noted that I have a 2.5" non-factory riser on the Trailblazer, so the angle is definitely not as forgiving anymore. However, the OEMs were factory originals with 90,000 miles and lasted a few years after I previously picked them up. Replace them with these. Very disappointed, I should have spent more on MOOG
