Re: anyone used expanding foam in there cab ???
I too have been wanting to do this for a while. Have you looked into the structural foams at all? I have been thinking about filling the A/B pillars and possibly other areas to make sort of a built in roll cage out of the existing structure of some of my vehicles. I am a ways off from actually pulling the trigger and doing any of this on any of my projects, but you might be interested in looking into it.
They are using foam to fill new cars both to quiet the interiors, and to make the passenger compartment more rigid, There are different types of foam for each application. |

Re: anyone used expanding foam in there cab ???
Here's a link about a comparo on sound deadening. Check it out. Oh, it's a lot of reading material, but it explains a lot.

Re: anyone used expanding foam in there cab ???
Here's what it looks like inside there in case you're going to have a go at this. You've got that lip in the back to contend with.

Re: anyone used expanding foam in there cab ???
I find it really ironic that someone running a 468 with straight pipes coming out in front of the rear wheels is that concerned about sound deadening.
![]() I think I know where a lot of that noise is coming from! ![]() I would think that it would be a lot of work for a minimal amount of difference. New trucks are much quieter, but all new trucks also have full headliners and pillar covers with WAY more insulation that you could get in a truck with a bare metal inside cab. I'd think there's no way you ever get one of these trucks as quiet as a new one.

Re: anyone used expanding foam in there cab ???
I'm crazy - but not that crazy! There was a large dent in the top of the cab and we decided it was easier to swap skins than it was to pull the dent. Click the C20 resto thread below to see more.

Re: anyone used expanding foam in there cab ???
Just a thread bump.....
Note to All; Do Not Use that Foam Insulation. Someone put it in the cab back corners. When I pulled the stuff out, the foam was dry, the metal was wet. It holds moisture. Posted via Mobile Device
