I have a 2003 Dodge Ram 1500 4.7L SLT Crew Cab 4-Door and need help finding out if this piece is even meant for my truck or not. Here is a link to what I found but it does not match my part number on what I have..(Current Part Number: 55350992AD) & (Supplier Code: 19593 D)

I need help figuring out what this heat shielding is and what it’s called!? It was on the undercarriage of my truck right by the transmission but I don’t know if it’s a transmission heat shooting or what it is I’ve tried typing in the model number and it’s a silencer floor pan front tunnel which is discontinued on moparpartsgiant.com.

This comes up on MoparPartsGiant.com as a Silencer-Floor Pan Front Tunnel which is Discontinued on the website but was wondering if I could possibly just replace it with a strong adhesive heat shielding from Amazon.com or Rockauto.com. Tag Says DR TUNNEL(Current Part Number: 55350992AD) & (Supplier Code: 19593 D)

 

Yeah, it's just basically insulation for noise/heat. Any product designed for the same task will work fine, it just won't be custom contoured for your floor. No big deal.

 

HeyYou I appreciate your reply I’ll definitely order some thermal shielding/ Sound Deadening material from Amazon and get it placed on my truck then! I’m just confused on how this shielding fell off in the first place maybe I messed it up when driving through flood waters that were up to my windshield a while back. It doesn’t matter now anyway but I do appreciate you taking time out of your day to respond!

 

LMAO.....that's the tunnel insulation over the driveshaft, mine ripped out years ago. It's discontinued, but if you contact a dealer they can tell you if anyone still has one in inventory anywhere.

 

Arguments will go both ways, but in every vehicle I have ever owned, if the sound deadener or heat shields started coming off, I threw them out and never looked back. Haven’t had any issues with any of them with them removed.

 

I can understand that! I just wanna be safer than sorry if something was to go wrong honestly, plus too I have my exhaust exiting out under the cab of the truck before the rear passenger side wheel and with it being so loud and under the cab I need to add some sound detening material especially on the interior of the truck cause I removed the rear seats and its just insanely loud while driving. I do appreciate your response here and hope to see you around more when I start the custom interior project for the backseat section!!

 

Are you going to remove the front seats and take up the carpet?

 

Yes I am I’m going to replace the carpet cause or stains and water damage! I’m also adding sound detaining insulation down fist then either add a new carpet but I’m liking the idea or a hard plastic liner.

 

I may be wrong, but seems like that came from inside the tunnel, underneath the truck, not in the cab.

OP, don't go buy a new piece. Just get some peel n stick heat insulation to re-cover it and put it back.

 

Great, that will make a big difference in sound and heat.
For sound deadening, a lot of people go with sheets of sound mat, the kind with the rubber backing (dynamat). Also take a look at the butyl rubber-backed flashing for door and windows. I can not tell a difference between sound mats and butyl flashing, and the flashing is much cheaper. Spray on sound deadening/undercoating is good too.
With the carpet out, it's a great time to run stereo wiring if you have an aftermarket system, or plan to in the future. Run the wires under the sound deadening to protect against chaffing.
If you are going to undercoat the drive tunnel, be sure to get the metal clean before coating. Wipe area down with rag soaked in alcohol as a final cleaning step before spraying the undercoat. Also put plastic sheets over your drive shaft and exhaust to keep them clean from overspray.
