Bought set of struts from these loosers and they will not stand behind their product! I purchased a set of 4 struts and shocks for my 2017 Buick Encore and two for the front of of my 2017 Honda Ridgeline and have no problem with most, but the front of the Buick struts make a noise sometimes when I hit a rough spot in the pavement. I contacted them and they are of no help. They keep insisting that I provide evidence of the issue. I have no equipment to monitor and record the issue when it happens so they have provided me with no help. These shocks are only a few months old and I have doen repairs to all of my vehicles since I was 16 and am now 69, so I know a little about parts and repairs. If Shockmasters cannot stand behind what they sell, their warranty is worthless. I will NOT be buying from them again and will advise all against them!
