Take your mobile entertainment on the road with the new RAM® Torque™ handlebar and rail mounting base. We’ve paired a Torque™ that accommodates large bars from 28.5 to 38mm in diameter with a short length arm and diamond base so that you can connect any of the RAM Mounts cradles or anything else with the AMPs hole pattern. Sizing inserts are included to provide a snug fit and offer additional protection for the rail. The mount utilizes nylon-insert locknuts to prevent loosening in high vibration environments. This low-profile mount is the perfect way to secure your personal electronics and small accessories in any high-vibration environment.

This arm has a socket at both ends that accommodates 1", B-series ball bases - RAM socket technology allows for almost infinite adjustment and perfect viewing angles.

The Diamond Plate measures 61.7mm x 33.3mm (2.43" x 1.31") and has a B Size 1" Ball. The plate has two holes 48.5mm from centre to centre, which matches the industry standard AMPS hole pattern and will connect to a large variety of RAM Mount and third party cradles.

Great product - Add foam product for complete solution
Model: 36 SqFt(3.4 SqM)
Used in two cars with speaker upgrades. Easy to install but get the roller for assured adhesion.removes "tinnyness" from large metal resonators. Use with foam absorptive material for a complete system.

Great Product for noise reduction in Auto Use.
Model: 36 SqFt(3.4 SqM)
I use this on many builds to dampen the metal echo in cars, vans, and trucks. Just one sheet in the center of a body panel is a huge difference maker. You can also cover the entire surface and get added insulation value. The noise is greatly depleted and it's easy to install with a roller tool. Looks Great when done. Good Product I will use again!

Great sound mat for the price!
Style: 50 mil 50 SqFt, Style: 50 mil 50 SqFt
This is a good product. Many people go with KILMAT because of the value to price point. I did as well. When you clean the surface (in my case it was all painted metal) this stuff sticks very well. I do recommend you use a seam roller of some type, I used Lumiteco 3 piece roller set. This will help with adhesion and mostly flatten the overlapped edges. It also helps you see where you have rolled as it leaves little grooves. The difference when we had no sound mats and after was very impressive. We haven't finished our install yet and it is quieter than when we had an interior in the van. There are thicker mats available in other brands, but this will work great for our van build, but this helps keep the weight down. It is quality material, just be careful when you are removing the backing, the edge of the foil face can cut you. I suggest you layout where you are installing the mat and cut to fit. From what I have read, you don't need to cover every inch in the vehicle, just spot install for a big difference. I chose to cover most surfaces to help keep sound out when we are sleeping in the van. We haven't finished putting the van yet, but we have driven it around and been very satisfied with this product.
