Well I got my skid plates from GM parts direct Thursday. I decided to order the truck without them, since they wanted nearly $150 for them. Why I dont know but that's besides the point now. I ended up paying $94.00 for them. They're very very heavy steel and will get the job done!

 

 

BTW----I did order a skid plate from a 2000 off of ebay. Keep note that 03/04 hd's are different from older trucks. That's what I was told from gm parts.

 

 

I'll get pics soon!

Also, the 1500 T/C skidplate is different than the 2500 series part.

Maybe they mount the same, just a different design or material. The OEM skid plates on my 01 are plastic and leave a big exposed area at the rear of the engine bell housing area. I've thought about custom fabbing some 1/8"- 1/4" aluminum plates, but haven't done anything yet. Some pictures would be nice when you get time.

How/Does it interfere with the oil drain plug? I have heard it makes it more messy to change the oil. Also what all does it cover/protect?

It doesn't so much interfere with the drain plug, but the stream of oil as it starts to taper off. My '03 1500HD likes to fill the skidplate with oil at the end of its drain and leak out the hole in front making a beautiful oil slick on the garage floor. I have started stuffing a few paper towels at the edge to keep the oil from traveling forward and it is working well so far! Had thoughts about just cutting 1" off the back of it, though.

That was one bad part of the skid plates.....messy oil changes. But, I replaced the oil pan plug with a Fumoto valve and now I don't spill a drop. Hook a tube to the nipple of the valve, flip the lever, and drain into a bucket, pail, whatever. It's nice.

Could you please quote a link for these skid plates. I am not having any luck finding them at www.gmpartsdirect.com

 

Thanks

I never heard of a plastic skid plate. It sounds like a splash guard to me. I am not a big fan of skid plates as I do not like draging my trucks bottom anyway. My 2000 K3500 Classic is pretty clean under it with nothing really sticking out below frame rails. On the SIlverados GM went to a external crossmember brace under tranny which is a poor design and a great brush of rock catcher. My guess is this design saves them some labor during assembly and repair. Also if you use alumimun, use 6061 as it is highly weldable as use T3 level of hardness (not T6) to reduce tendancey to crack under impact and use at least 1/4' thickness and preferably 3/8"

snoman-The term "skid plate" I use is probably stretching it. You are correct in that it is probably more of a brush guard. It is a 2 piece deal. Front one attaches to the frame cross member behind the front bumper and curves down to the front suspension crossmember. The rear piece attaches to the front suspension crossmember and extends to the transmission crossmember. Both are plastic. Neither would do much good if I would skid/drag the frame on rocks, but I guess it could prevent a branch from getting jammed up in the crankshaft pulley and throwing a belt. Or deflect any road debris such as tire rubber that may get thrown up in there. The front of the engine is pretty exposed without them.

We have a 17 ton press brake at work, so if I can find some material, I may try to fab something up. I'll keep in mind the specs you mentioned on the aluminum, but I'll probably just use what's available. I would need at least 1/4" material to support any kind of weight from the truck, but I don't do any 4 wheeling since mine is 2wd, but I have been known to take on a cow pasture or field with tall brush to get where I need to go.

 

Mr2500HD-Any pics, part numbers, etc. would be really cool!

I fully understand. I would use 1/4 inch then as Aluminum cracks or breaks when overloaded in a impact so you want to go big even on a 2wd. Stay away for 7075 as it can be very brittle and 2024 T3 will work nicely if you do not plan to weld it ever. Remember when you start a bend with these alloys, do not stop motion until you get angle you want as they will work harden greatly after being bent (you may already know that )

I've found the best way to keep oil out of my skid plate when doing an oil change was to install a Fumoto valve. On my truck (and I think most newer GM trucks), due to the recessed drain hole, I also had to buy the "adapter" thus adding on an addition 1/2" to the valve. I got the one with the nipple so I could stick a hose on the end and put it into my drain pan. No mess on the garage floor anymore...

I'll have to definitely remember to get one of those valves if I add a skid plate to mine. I'm still trying to find out how much of the undercarriage it covers. Is it just the engine oil pan or does it cover more?

      The Peckish Synapse

      By Grumpy Bear · Posted

      You're better read than that Atlas. 😏   British science fiction writer Arthur C. Clarke formulated three adages that are known as Clarke's three laws, of which the third law – that "any sufficiently advanced technology is indistinguishable from magic" – is the best known and most widely cited.   Stribeck and the pivotable Hersey Number isn't voodoo nor snake oil. That part is physics. It's what marketing and bean counters do with it that is snake oil and voodoo.    Stribeck is the relationship between Hersey and the Coefficient of Friction. Within the Hersey Equation if viscosity and viscosity is 'Dependent' on.......heat.......and.......viscosity index or the temperature to viscosity slope.    Specifically Hersey is the viscosity AT THE TEMPERATURE IN THAT LOCATION FOR THAT SLOPE.   Hydrodynamic lubrication exist when the film thickness in the location is 3X the Ra roughness of the surface. This is irrespective of the hardness of the substrate. To obtain that thickness X viscosity is required for Y velocity at Z load. That's a lot of moving parts. It is also impossible to maintain in an ICE but nearly possible with a turbine under constant load.    What does that mean? Error heavy and operate light. Wear is inevitable but the rate of wear and the milage obtainable are a function of prevailing conditions and HABITS. The only penalty is viscous drag and at fractions so low as to be well worth the effort. Double the life, half the manufacturing carbon foot print. Greed is the only impediment.    The materials generated by SwRI are the RESULT not an estimation or a hypothesis.    Don't delude yourself sir, EV's have as many pitfalls as ICE's. We just don't know what they are yet and it will take longer to sort as MARKETING and GREEDY CEO's have had more time to polish the turd they are selling.

      You can always count on greed to prey on ignorance and stupidity.    Friend bought a 2019 Ford Flex and asked me about using Valvoline R&P 5W30 in it. Told him give the miles on it and the fact it wasn't yet using oil that it was a good plan. He uses a Valvoline quick change shop for his oil service.   First they tell him that isn't the oil the OEM recommends. He told them he didn't care what the OEM thought. Then they floated the, "But it will void your warranty"    His reply was it's a 2019, there is no warranty and informed them their knowledge of the law was lacking.    Then they tell him 'But it will ruin your motor"!.    Mine to ruin he says. Finally they give in and charge him 150% the semi-syn price    Point it the brainwash is so embedded that even the service industry is drunk on their swill. The public is right behind them. Echoing the same lies on every forum and media platform. If the end goal is indeed EV then I'd say that ship is about built.
