I am looking for a guard that goes under the Suburban to keep mud, water,etc. from splashing up at the motor, etc. I saw it on a website, but can't find it now. Need it for a 05'. Any leads would be great. Even if you only know the name of this item. Thanks

I believe what the thing you are describing is a skid plate. It bolts to the bottom of the chassis under the engine to keep crap from flying into your engine when your offroading or going through high grass and stuff.
