UPDATE WITH PHOTOS For anyone wanting OE metal skid plates for their 2019-2026 Silverado 1500 or Sierra 1500

*SEE BELOW FOR UPDATE*

So, after hunting on the internet with a rhetorical shotgun for skid plates, I decided to do some research into OE parts.

Here is what I found.

for the metal skid plate (splash guard) from the bumper to the first crossmember, the part number is 86803306. Can confirm through ACDelco’s website that it is metal. I’m not sure what kind. When shopping through GM dealers, DO NOT INPUT YOUR VIN. I’m currently battling it out with Chevy Parts Pros and told them to pound sand if they won’t send me my part. Does NOT FIT DURAMAX OR 2.7L MODELS UNLESS YOUR ORIGINAL PLATE IS p/n 84125967. This plate is factory on vehicles with “enhanced tow”.

for the steering gear plate, part number is 23385004. It is 1/8” steel, I believe.

for the transfer case, part number is 84699480. This shield spans the gap between the trans crossmember, and another behind the transfer case, uses (4) m8 x 1.25 x34mm bolts and u-nuts to secure into place. Fits 2019-2025 models, 4x4 only. It’s powdercoated 1/8” steel.

you can get the steering gear shield and the transfer case shield in a set through GM accessories under “off-road skid plates set”, but I found it cheaper to order some off-brand bolts/u-nuts and get the parts individually.

cheers!

********************************************
My parts finally arrived.

86803306 does in fact fit in place of the plastic shield, and is made of the same material as the trail boss skid right behind it covering the steering gear. I do believe it’s either aluminum or mild steel.

I took the air deflector off the bottom of the bumper to mimic a trail boss. The plate bolted right up and I had zero issues with install. Took 10 minutes with a ratchet, extension, and socket.

I bought a set off Amazon, they were metal and about $100.00 for the oil pan (bottom piece) and splash shield (front piece).

Or get the Rough Country steel ones that replace the plastic front piece and aluminum bottom piece for under $200.

Are these if you don't have the Z71 package or overall better and stronger coverages?

I know that big plastic piece under the front of the engine is BS what one are you guys replacing that one with?

TIA

These look excellent for the $

Yeah, nice cheap improvement over stock plastic. The AEM ZR2 won't work because the bumper is different and won't mate up to the standard bumper. I added a couple brackets at the very front since there's nothing but the two side pieces to support it. If you catch something with the very front edge, it can bend down. I pulled it off when I was having the 6.2 recall done and then it got cold and snowy. I bought some red acrylic to put behind the RC cutout in the front plate. That way it will keep crap from getting in there and be a little showy with the red. I'm also going to bedline it as the stock powder coat scratches pretty easily.

Yes, I believe so. 86803306 is the plate I was referring to that replaces the plastic plate behind the bumper that bolts to the bottom of the rad support and the crossmember where the steering gear bolts up. See photo above.

I like that idea, I am also trying to stay factory where I can if it’s an improvement. I know, this doesn’t apply with engine or trans internals though

I will say, I’ve been giving the differential skid a long, hard look, too. I’ll be doing a little overlanding this summer on my camping trip, so I’m just doing what I can to protect my investment.

It looks like a front bumper and grille will swap to any trim from ZR2, although I may be mistaken.

My 2018 3500 Z71 had a metal skid plate on the bottom of the oil pan and a plastic splash shield from the engine cross member (front of the bottom metal skid plate) up to the cross member below/under the radiator, this plastic piece was cracked at the top mounting points. What I bought replaced both of those pieces with metal.

Looks like that fits the previous body style. I have a 2024 1500 T1, friend.

Thanks, I do have the Z71 factory skid plates but that plastic piece is crap and I do have that to replace.

Thanks!

86803306 will fit if the original plastic one is 84125967. 86803306 is aluminum or steel I believe. The one @asilverblazer posted was for a previous generation (2011-2019 2500/3500) truck; K2 I believe. The one I posted fits a T1, 2019-current.

The one that replaces the front from the bumper to the fist crossmember is 86803306 if you want factory. About $140 plus shipping is the lowest price I’ve seen.
