Review on 🔧 GM Genuine Parts Engine Mount - 15854940 by Steve Cooper

My 2013 GMC Sierra had intermittent "rough idle" or shaking around 95000 which was bugging me up to 126000 today. None of the brackets I removed looked terrible, although the driver's side was even worse. There were a few cracks and what appeared to be a mark where I suspect hydraulic fluid had leaked from inside the mount. Very glad I bought and installed them and finally solved the idle issue. Note: I purchased and used these factory mounts in place of the much debated H3 mounts. I can tell you that I've only tried the H3 mount on the driver's side and that made things worse. I removed the H3 mount and installed two of them. The guys say it won't last as long as h3 mounts, we'll see. At the moment she drives with no problems
