2018 Z71 Skid Plate Part Number

[Oh Kee Pah]

Hey!
Thanks for checking back in. I'm still not sure about that front skid plate needing the z71 front fascia. I was up under there (truck not off the ground unfortunately) and I located the rear 2 connection points. Those connect to the main frame of the vehicle. For the front connections, I couldn't find the exact points. I'm not totally sure it does connect to the front bumper fascia because I had my hand up there and a good 1-2" of space seems to be between the front bumper/fascia and the edge of the plate. Grabbed some photos: see below.

I also dug up a PDF file I had from quite a while back regarding the z71 front skid plate. There's 2 different front skid plates out there. Sounds like you have the right one; one I believe is only made of "heavy duty" plastic. Take a look at the schematic below. I think it's a bit tough to make out but it seems that the 2 front connection points are through the front of the skid and attaching to the front of the vehicle frame. It sounds like you know what you're doing so I bet you can take a second look.

Keep me posted.


Also - totally agree with the overlanding type build getting out of control and kind of poor looking if you start doing too much, especially up front. And like you said, the IFS is going to get you only to a point in terms of difficult off road terrain. I guess it all comes down to our individual goals, needs, wants and finding a suitable place somewhere in between it all.

Still, I like the idea of a swing rear bumper and where you could get the tire and gas/h2o back there. Probably really a custom thing unless you happen to be good with welding, paint etc.
I've seen a really cool roof rack system, but not cheap.

I've also seen the idea of removing the 3rd row completely and then modifying the rear cargo/3rd row to have a pull out drawer, other kind of customized "hidden" storage and goodies.
There is a member @Tozan who has an earlier model Tahoe but has some great overland/off road ideas and mods. Maybe want to check him out...

what is the part number for that forward skid plate # 6 ?? searched that same vin and it only shows the plastic one or the optional aluminum ones neither of which are that one.

**also that referenced vin code in the pdf photo does not appear to be a valid vin #

It has taken me some digging and "remembering" my own research to find you an answer to this one. For some reason, Chevy was a real pain in providing me a straight answer. when I was working to source this part. I actually ended up ordering 2 of those plastic skid plates before I got the correct part. A guy that worked in the body shop of a local dealer was the one that actually figured out the correct part. He's the one that supplied that PDF printout (with the weird VIN# from previous post). Really great guy but now works at Dodge - bummer!

I think it's pretty safe to say that if you are seeing the front skid plate for less than $150, it's the plastic one. I paid $233.03 + dealer labor (install) + sales tax.

I purchased GM Part# 23475140


Examples of some online purchase options I found today for this part#:

Here's a copy of my receipt & invoice from Chevy dealer:


Hope this helps!
Totally agree that finding your way through the maze to locate this part is confusing.

Maybe a photo of my front skid plate would help too...

Looking back at the earlier posts on this thread; it seems we have the plastic front skid plate and 2 different AL (aluminum) front skids in the mix. This is the one that I'm running and I DID purchase through the dealership and it was GM Part# 23475140

and yours looks like the one in the original post in this thread?
because when I search that part number you just provided the generic part photo looks just like part # 23135960

answered that question, lol

So yours goes around the little cups on the front of the frame? I don't see a bolt hole in front of them did you have to drill holes for the bolts?

IFS... I think solid axle set ups are way over rated in today's 4x4 market and not really any better depending on what you are doing with it. Solid and IFS both have their advantages.

Do you want a serious rock crawler? After you spend $10,000 or more on your solid axles they can do pretty good crawling. Your vehicle will likely be very limited for camping and forget comfort. Also doing serious crawling things will break pretty often too.


If you want to see some real extreme 4x4 check out the Hammers all of them are IFS and RFS. they are total badasses at covering really rough terrain. I think you will have a very hard time convincing them a solid axle is better...

I wonder why just about every quad and side by side is IFS and RFS? Most likely because it is easier to design build maintain and it works better. They also have better ground clearance too.

Now lets talk about going fast off road that is what I like. Nothing like ripping up a back road or desert trail in excess of 75 mph... Most Trophy trucks have IFS and many have RFS too. Why, because it works and is smoother than most solid axles...

Lets be very clear overland has nothing to do with rock crawling and 99% of what you will encounter overlanding and camping is not going to be over terrain as difficult as rock crawling. Crawlers would be very uncomfortable in a long trip.

Overlanding does entail for most of us 300 to 1000 mile off road trips at a time so, passenger comfort, fuel range, camping gear, water, food tools, parts and some like mine even have refrigerators. My Tahoe has 11 inches travel up front and around 15 plus in the rear and as much or more articulation then several rigs I travel with. A locked rear end 4h/4Lo makes it a very capable rig. I run with jeeps and all sorts of other 4x4s that are considered very capable with no problems.

Related to this thread I do not have any skid plates right now and they are not very high on my priority list. The big skid plate up front is not really protecting much at least not on a GM900. The limitation of your suspension right now should keep you off most stuff that would damage anything under there.

True but some road debris like this can ********* your vehicle, I hit these at about 60mph maybe slightly more, one punctured the tread of a tire entered the tire and then exited the tire ripping the splash guard in half, one went thru the running board and another went thru and lodged into the wheel well luckily that was just the right rear wheel area if it had been the drivers side it could have punctured the gas tank, if it had been up front hopefully the skid plates would have done there job, not sure though somehow the rear ac lines were missed

I am not sure what those are but, I don't think you would be hitting them on a trail.. It does go to show there is no telling.. lol I once hit a 10 mm Craftsmen wrench we found it inside the tire... That was a surprise.. Good part is I still have it in my tool box today...

Those are 2 pieces of rebar that were laying in the road, there were more scattered in the road since they were virtually the same color as the road I didn't even see them until it was too late all I head was thunk thunk thunk from under the truck as I passed over them this was about a mile from home as soon as I pulled in the driveway I heard a grinding noise got out looked and the truck was harpooned and the tire was hissing air, luckily there is a tire shop about a mile and half from me so I jumped back in the truck and managed to make it there before it went completely flat, one entered the tire and ripped the wheel shroud, another entered the running board and went up thru the shroud and become wedged and another was up higher but had entered thru a gap in the body and then punctured I don't what can't see it beyond the outside somehow it missed the rear ac stuff

Wow that is some crazy stuff glad you are OK.

The front non-Z71 skid plate attaches to the round tubular crossmember at the front of the frame. Same place the plastic piece attaches. It does go around/behind the frame cups.

Whoever attached the plastic piece from the factory decided to do a superior job-aka tighten until it strips and then tighten some more! I ended up drilling out the holes and put a couple of rivnuts in there.

I ended up running over a blown semi-truck tire on its side. Following a moron in a Honda Odyssey who just cut me off to closely. They swerved and I didn’t have time. Truck just went whucka-whucka. Glad I had the skid plates! (Why do Honda Odyssey drivers think they are driving a race car? Most drive like idiots...)

Robert's skid plate is different, I know how these mount up I have the same ones

Speaking of Brian O'Connor I just watched someone in front of me drift sideways on the freeway at 70 avoiding a muffler in the road. While I had to straddle it and get lucky but have NO skidplate yet on this damn yukon. Anyone know whether the bolt holes on the 15-20 denali line up with the Z71?

Same frames, same holes.... just not threaded. They are all there.

The interstates of America almost require skid plates nowadays. I added the PPV valance to my 2015 tahoe after hitting a semi truck tire on the road in the exact same manner as you described - cost $1,400. Probably would have avoided much damage if the OEM air dam didn't come so close to the ground. Can anyone speak to whether Part #23475140 (the part shown in the black Midnight edition) will fit on the LTZ with a PPV valance?

Just joined the forum the other day. I've had a 2007 Silverado LT and finally had to trade that and my work car in for a vehicle that's better for our family. Decided to Join the tahoe family. Anyways, Glad to move from the silveradosierra forum to the Tahoe Yukon.

I have a 2020 Tahoe LT. I'm not happy that there are no tow hooks and the air deflector scraping the ground every time I pull in my driveway. I've already researched adding tow hooks with the different fascia piece that has the holes for them.

I'm still deciding whether to trim the air deflector or spend the money and get the PPV deflector. Now to further complicate things I started researching if the z71 front skid plate could go on my setup and if so which route would I need to go with the lower air deflector. Skid plate isn't too important to me and I'd like to make a move on the tow hooks and lower air deflector soon before hunting season is here. Does anyone know if the z71 skid plate works with the LT bumper? if not, then I'll stick to tow hooks and air deflector and be done. Thanks for the help.
