Heat shields on 2500HD

[Steve-Maine]

Got bad off and undercoating it. Do I really need the heat shields on bottom of bed ? Thanks

[Earl Cordova]

Yes.

GM would not have spent the money on them if not needed it gets hot underneath when running and can damage box paint and cargo inside while driving. Who ever undercoated the truck shouldn't have put undercoating on heat shields and they should not be removed for the undercoating.

Come to the north and see how many trucks and cars still have their heat shields intact still.

 

A shield shield by a firewall is more important than a heat shield by the underside of the bed. I can't tell you have many heat shields I've removed on cars and trucks because they rust away and rattle all over the exhaust and bang on stuff. Years later I still see those cars driving around.
