Description
 
JNMDamp-Pro is not a mass loader. It is a constraint layer viscoelastic damper that converts the vibration energy in to low level heat. This conversion of energy makes it 300% more efficient than traditional mass loading tar boards and asphalt mats while weighing half as much!
Stopping the vibrations on your engine lids is much like stopping a noisy wind chime with your hand. Once the vibrations stop, the noise stops.

First, the foil acts as a radiant barrier, reflecting heat back towards the source. When used on the firewall, this prevents as much heat from making it in to the out side of the engine lids. Less heat means less hazard for your safety .
Second, the foil heat shield on JNMDamp-Pro is dissipates heat by increasing the surface content, allowing for thermal dissipation and reduction.

No noticeable difference July 1, 2015
Reviewer: jolfstn from Seattle, WA USA  
I purchased this item a couple days ago, it showed up quickly, appears well manufactured and the adhesive works very well.  Easy to install and heavy substantial material, this is a quality product.  Unfortunately, I noticed no noticeable sound difference.  Using a guitar sound meter, engine noise registered a couple decibels quieter after installation. There are a couple possible  reasons for this.  1:  I have crappy hearing due to my career spending years mere meters from massive marine diesel engines  2:  This is a new motor and is already fairly quiet.  I'm giving it 3 stars because this is NOT a criticism of JNM or their quality products, merely my personal experience with this particular product.  I've purchased from them in the past and have always been happy.  I will continue to do so.  So should you.

Reviewer: Jaguar from Houston, TX United States  
Gear noise is excessive on these chinese engines and this damp kit does a good job of reducing the unwanted sound.
