Grill with less crome was worth the Z71 package price to me lol

 

I would go take a pic and knock on mine to see what they really are but... Its 14 degrees outside lol

 

Sent from my Note 4 on Tapashit

 

 

Indeed. I ordered Z71 purely for the "less chrome" look (although I then added some by going LTZ). Couldn't care less about skid plates.

My High Country 4x4 came with the front skid plate, if you can call it that. It is just a plastic shield from the radiator support to the front cross member. I think the brackets listed in your part

Now when did they come out with this and better yet why don't the Z71 trucks come with them from factory? I know several of us have discussed wanting/wishing GM would have put the metal skid plates a

Can anyone confirm the actual bolt size for the two under-engine skid plates as well as the transfer case skid?  I'm seeing conflicting reports.  Either M10x1.50 with a 25mm length OR M8x1.25 with a 30mm length.  Which one is it?

This is the part number (bolts) I used when I put the metal skid plates on my truck.

Yes I know that's a dealership part where they charge you nearly $10 each per bolt, I don't enjoy getting raped unnecessarily 😄

That's the information I thought was correct, but I'm being told it's a different bolt by another guy.  I haven't installed my plate yet and the bolts and tap I bought today are for 10mmx1.50 thread as you said.  So, if what you are telling me is correct, what I bought is correct.

Not sure if this a dumb question (most are), but have you taken one of the factory ones out and compared?

 

I bought extras because the "metal" skid plates take 8 bolts, and the factory plastic shields take 6 (if I remember correctly).

I just ordered the skid plates yesterday.  I haven't taken any bolts out yet.  You are correct from what I hear the front metal plates, which there are 2 of, use 4 bolts each, and the transfer case skid uses 4 bolts.  So as of right now I have more than enough bolts to complete the job.

      This is interesting. My quote tagged here is different from my original quote. After I’m driving them longer. That isn’t me. I don’t talk that way. I definitely wouldn’t express myself that way. Interesting.

      What have you done to your K2 today?

      By UrbanRage · Posted

      I have the same running boards on my truck and I do agree they are bulky. I also find myself stepping over them when getting in and out of the truck. Besides providing protection to the rocker panels, they aren't very useful.  I will be replacing them soon with the Amp Powersteps.

      Vehicle Payments

      By ChristopherDobson · Posted

      Monthly payment is only part of the equation. With today's prices and interest rates, I'd look at the total monthly cost: payment, insurance, registration, fuel, maintenance, and expected repairs. A vehicle that fits comfortably into your budget is usually the better choice than stretching for a higher trim. I've also kept my vehicles longer over the past few years. New cars have gotten expensive enough that driving one for 10+ years, while staying on top of maintenance, often ends up being the most cost-effective approach.

      OCI, not when but why?

      By Grumpy Bear · Posted

      10 Ford and Chevy engines proven to reach 300,000 miles   You may note a common 3K OCI on this list of gas motors. I skipped over the diesels. Dh'O.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By jake111 · Posted

      Thanks newdude!  By the time manual selection is needed, I'm probably too much of a control-freak to depend on the transmission sensing braking to activate automatic downshifting.  I would be anticipating the situation and already be manually downshifting.   This truck replaced a 2004.5 LLY diesel with the Allison 5-speed.  Putting it in T/H made noticeable differences (when the torque converter locked, upshift points, downshift behavior).  On this 2024 gasser with the 10L1000 I haven't been able to detect much, if any, difference.  Ok, I can never tell now when the torque converter locks up.  But I also don't notice differences in shifting.  For downhills, I've probably already manually downshifted by then anyway.  Since it's also more awkward (than the 2004.5) to engage/disengage I don't even bother.  Or maybe it doesn't really matter with just a 3k lb. camper in the bed?   Thanks also for the list of reasons the charging system might select various voltages.  However, what I am seeing doesn't fall into any of those categories.  It very definitely, and very consistently, rises after coasting/braking.  Maybe not immediately, but not very long after coasting/braking.  Very consistently drops voltage when no longer coasting/braking.  It might also be interacting with the camper battery charging (I might disconnect the camper and see if it changes the charging behavior).  I also need to recheck turning on headlights for when I want to force it to charge the camper.   Another JR, in June I converted the camper to LiFePO4.  Since it's not a good idea to try to charge lithiums directly using truck, I installed a Victron Orion XS DC-DC charger (which BTW is AMAZING!!).  Being cheap, I only had to buy that one item (besides the battery, of course) to do the conversion.  The camper OEM 120v battery charger (only 19 years old and works perfectly) and the truck feed the input to the DC-DC charger (not at the same time).  But I didn't want the camper charger feeding back to the truck so I kept the old separator.  I considered replacing the separator with a 30amp diode but that means more work and might add another 1/2 volt drop.  One thing that surprised me was the voltage drop over the long 10awg wire run, so I can only charge smoothly at 8 amps (because the DC-DC charger is completely configurable).  Another reason I don't want an added voltage drop with the diode.  I might also be a little lazy but all this work is being done under the sink with a small cabinet opening.
