Merchant Automotive Heavy Duty Motor Mounts 11-16 GM 6.6L Duramax LMLThe 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

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.

Perfect casual Friday shoe with great comfort and style
Size: 10, Color: Optic White/Egret
These have quickly become my go-to shoes for casual Fridays at work. The fit is true to size, and they’re both comfortable and stylish without trying too hard. They pair really well with jeans or khakis, so they’re easy to dress up or down depending on the day.

Narrow and small
Size: 10.5, Color: Black/City Skyline/Egret
I mostly chose these due to the foam rubber soles, as I was looking for a more comfortable sneaker. They are more comfortable and the quality looks decent, too, although I wish the leather wasn't so shiny. The fit is quite narrow, and while they're okay for my narrow feet, I still wonder if the wider fit would have been better. This is my 2nd pair of Cole Haan sneakers and the first were too small. So this time I ordered the next size up and the fit is not much different, so I'd say they run small all around. Despite that, they're big enough and are still quite comfortable. Finally, the laces are too short. This is probably by design, so they're not dangling around, but I find them difficult to tie. They're nice, waxed laces, but they just need to be long enough to work with.

Young professional son loves them! They are very comfortable and stylish. They fit well with the new "business attire" standards and work well for going from work day to evening social.
