Might be a good idea if you go crawling around in the rocks..........
Absolutely, but it was also finding that my OE plastic pan was already cracked around the bolt holes on a nearly new truck. I am sure it will do the job for the moment but it caused me to do some forum searches only to find that the cracking was common. A new GM plastic pan is not very expensive but it also is not going to solve the problem.

The problem is the skid plate is plastic and people over tighten the bolts. I have a lbz with that same type of skid plate. When I first got the truck I took that plate off a couple of times and must have over tighten it. I started noticing cracking around the bolt holes. What I did was not tighten the bolts so tight and it lasted many years like that. If you worried about the bolts coming loose, you can use silicone on the bolt threads and it will prevent the bolts backing out. Or use a little blue locktite.
I have never had a problem ever since. All i started doing is not tightening the bolts so tight. Never used any thread sealant. I just recently install a lift so replaced the skid plate with another factory plastic one.
On my 18, the skid plate is already cracked and I have not taken it off. The one on the 04 has been cracked since about 06 and still going strong. I think GM should have put metal sleeves in them to prevent the cracking.
