Review on πŸ”§ GM Genuine Parts Engine Mount - 15854940 by Steve Cooper

Revainrating 5 out of 5

Smooth idle, finally

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

Pros
