Metal skid plates?

[Silverado-Hareek]

Yeah i still haven't heard back from my friend in Texas he hasn't answered my last couple of messages on facebook. I'm not sure if he's just really busy at his shop or what. A coworker of mine has a plasma cutter and does some metal work in his spare time. I may explore fabbing something up with him. Sorry guys for getting your hopes up. I'll let you know if something changes.

Suggest going with .100" thk 6061 aluminum and precipitate harden to T62 condition.

Comparing 1010 Cold rolled steel to 6061-T62 the tensile strength is nearly the same, (53000 vs 45000).

 

6061 is fairly easy to work with, and is able to be welded nicely.

Powder coating takes well also.

 

 

S8,

I'm not going forward... too many people want to design their own. One guy suggested carbon fiber. He said he could do it and I should use it instead of steel. He also thought my estimate of a steel skid plate was too high. I figure a carbon fiber skid plate would be a bunch more than steel. Lots of suggestions, no one willing to commit.

Just got my metal skid plate for the transfer case but need to get bolts. Anyone know what size I will need?

I also bought the skid plate, parts guy said you want to buy the 4 bolts, no thanks (they were more expensive than the skid plate?) I tried numerous bolts in metric and standard both fine and corse threads and none would start so I got under the truck with flash light where the skid plate is supposed to bolt up to the transmission cross member there is 4 holes "but no threads" in the holes sooooooooo I don't know if GM is using some kind of self tapping thread type bolt or if it is not a Z-71 or skid plate option truck they just don't drill the holes at the factory? If you find out what bolts to use please post the info?

I told my dealer to install the plate if he wanted the sale and he obliged. The work order shows that the holes were tapped- not sure of thread pitch or size.

I tried buying stainless bolts but wouldn't work and ordered the GM part bolts that are self tapping $5 or $6 each

can you post a pic before you install them. I just want to see what they look like. Thanks,.

Sorry I installed it last week the bolts were just tapered threads I think they were $5 on quirkparts.com

I just checked Toyota, Ford and RAM (full size) and all these truck had front metal skid plates and not like the plastic ones on GM trucks.

Definitely want metal!!

That plastic thing that you broke is NOT A SKID PLATE. If you look at your front diff, now that the plastic splash guard is gone, you can see a steel skid guard. The oil pan is so far up in behind the cross member and sway bar that it doesn't need any more protection.

So there's a steel skid plate behind the plastic "underbody protection" we'll call it?

 

And you're not talking about the aluminum plate under the transfer case right?

GM part Number 23176881 for skid plate kit which includes both front plats as well as the transfer case plate. For the 5.3L and I believe the 6.2L as well.

My non-Z71 4x4 Denali came with the transfer case shield, so it's not only for the Z71 package.

 

And FYI, the GM bolts are self tapping. You're unlikely to find them at local HW store. My dealer sells them for $5.50 or so.

Do you know the part number?
