The OEM rubber motor mounts on your Duramax-equipped trucks are great for light-duty use. When you start to add some power to your truck, or use the truck off-road, these rubber mounts can rip or start to fall apart. Motor mounts that rip or break will cause excessive vibration or engine shifting while driving. This vibration and shifting can cause damage to other engine components over time.
These replacement LML solid motor mounts from Merchant Auto are a great upgrade for higher-horsepower engines. When it comes to motor mounts for your Duramax LML engine, you can choose from OEM rubber, performance urethane, or high-performance solid motor mounts. These solid motor mounts are going to give you the best performance and reliability for trucks pushing high horsepower numbers or spend a significant amount of time playing in the dirt.
While these motor mounts fit 2011-2016 LML engine-equipped trucks, they are mainly going to be used in off-road/high horsepower setups. Solid motor mounts can cause a little NVH, noise/harshness/vibration, while at a stop, that is usually taken up by rubber or polyurethane mounts.
Are My Duramax Motor Mounts Bad?
To tell if you have a bad motor mount, take note of how your vehicle is running. With excessive vibrations being one of the key indicators of bad or worn motor mounts, it can be a little difficult to differentiate between engine mount vibrations and suspension vibrations. To check your motor mounts, pop the hood of your truck, have a friend rev the engine while in park, and look for excessive movement. If you notice the engine rocking back and forth more than usual, chances are, your motor mounts need to be replaced. While factory motor mounts will correct this, these MA Motor Mounts will be a superior replacement that offers longer-lasting and higher performing polyurethane bushings.

I stay on your foot they don’t slip in your shoe
Number of Items: 3, Color: White/Neutral (3-pairs), Size: Medium
This is the only socks I wear Under Armour because they stay in place I wear a size 8, but they’re more comfortable with a large instead of a medium, but I wear both because I have them already and you can pull them to stretch them out a little bit
