I spent about 6 hours removing the seats and everything else in the cab and doors and place dynamat in it. The difference is amazing, when the windows are up you hardly hear anything in the cab except that lovely whine from the eaton, though it is considerably less.

Another thing I noticed was how crappy ford was with the sound proofing material inside our trucks, they only gave us about four lines of what I will call goo on the floor of the cab below the driver and passengers foot. Nothing anywhere else.

So I did the entire cab and double on the floor. I would recommend this to anyone who want less vibration and noise in the cab. It also helped out my speakers alot too the clarity has improved a whole lot.

After finishing in the cab I was looking underneath the bed and noticed that my truck has shackles on it, with the spring eye bolted to the top one which raised the truck as high as possible. My question is. Was this done by ford to increase the ability to carry load? or was this done by the previous owner. Let me know.

 

If there is more than one set of holes in the shackles, they are aftermarket. Also, the top set of holes would lower your truck, not raise it.

 

Thanks Stl01SVT. There is about 4 sets of holes. I did not realise that the top holes would actually lower the truck I guess I won't have to think about lowering the truck then

 

I've been wanting to dynamat my truck also. Is it really that much better though? Also how much did it cost you to do it? (Time wise and money wise)

 

it is truly a huge difference, especially when the windows are up. It is very quite in the cab and as I mentioned earlier the speakers sound way different the clarity is much better. A friend of mine gave me 20 feet of sound proofing so it did not cost me anything dollar wise. But to do it is time consuming. I guess a pain it the butt is more like it. But it is worth it

 

I have booku amounts of sound deadener in my truck. I would say at least 100 sq ft of it. I have a combination of Dynamat Extreme and Be-Quiet Brown Bread in mine. I think I paid around $125 for 75 sq ft of the Brown Bread. The stuff really does help out a lot. I do recommend it for anyone.

how much weight would this roughly add

 

20 square feet wont go very far - you must have started with more

20 square feet barely covered my doors and the back of the cab..

I recommend Raammat ( http://www.raamaudio.com ). It is just like Dynamat's top product but is only ~$1.10/ft². A layer of their foam will also help significantly.

I used about 60ft² just for my doors so I would recommend atleast 120ft² if you want to do the entire cab. This isn't something you want to install then not be happy with the results and have to do it again.

Weight gain on the doors was about 26lbs with 2-3 layers of Raammat BXT on the outside sheet metal, 1 layer to enclose the door, some patches on the interior door panel, and a layer of foam on the outer sheet metal and under the door panel.

 

Good advice. I used 2 rolls of RAAMmat. That got me 2 layers throughout the cab, excluding the roof and firewall. I also partially closed off the cab vent on the passenger side. Mucho exhaust noise comes throughout that little bugger.

 

so im looking at less than a 100lbs to do my cab?

 

I would guess around 65lbs.

 

Man, you guys like to waste money!

Instead of DYNAMAT, go to Home Depot/Lowes and buy a ROll of ICE SHIELD.
It is a rubberized mat that has one sticky side. (sound familar?) You can buy a rol of it for about $50.00 which is enough to put several layers (an inch think maybe) on the interior (including roof) of the lightning.

I used to use it all the time, when I had my competition audio systems in my, Grand Cherokee, Dodge Avenger, Dodge Daytona, and DOdge Shadow.
It works Just as well as Dynamat and is about 50-75% cheaper.

I think it is a 3-4' wide by 100' or 150' feet long.

 

sounds good will have to look into this
