I purchased for shocks from rock auto on November 2016. They worked well for about 7 months but then started bottoming out so i tried to get a warranty exchange form rock auto because at the time of purchased they stated it had a lifetime warranty. I was told that they no longer work with this manufacturer and will not honor the warranty and was to to contact the manufacturer. That is horrible and very dishonest and i will tell the world that rock auto does not stand by the products they sell.
