Anyone know the correct part numbers for the lugs and wheel locks for these wheels? My understanding is that they use the Bulge-type cone seats and I'm having trouble finding the right set of locks for them.

There are apparently two different sets of lugs for the Silverado/Sierra's mags. One that has a shallow cone and one that has a deeper cone. The deeper one apparently takes a 7/8" socket and has a larger overall diameter , the shallower one a 3/4" socket. They're both angled at 60°. These wheels take the deeper cone. I just can't find the part number for the locking lugs for them.

 

Thanks

Not sure that's correct. I actually bought a set of those very locks. After taking one of the lug nuts off and comparing them side by side the lug nut is definitely bigger around, and has a rim around the base right above the cone that tightens against the wheel. The locking nuts just sit down inside the chamfer/cone without contacting the meat of the wheel.

I tried calling the dealership today but couldn't get through. I'll keep trying, and worse case go to the counter when my plates are ready to be picked up.

Here's what my lug nuts look like. That rim around the base tightens against the wheel. The locks I bought and that you pictured don't have that, or tighten that way. And they're smaller in diameter on the business end.

But, I do appreciate you trying to help. If I can get a part number from the counter I'll post it here, whether I'm right or wrong.

Yeah, the locking ones are shaped differently at the top but the cone at the bottom is what is important. It is a 60 degree seat. I have those locks on my truck. I bought 2 sets of them. One set didn't have the paperwork with it to order a spare key. The other set was still in the package and has the code to get another key. I have put both sets on my truck with no issue.

But what wheels do you have on your truck?

My understanding is that both the smaller cone locks and the larger cone locks have a 60° cone. But the smaller ones aren't big enough around to make contact with the sides of the bolt holes near their top.

I went to the dealership today and they had nothing in stock, but the picture of the locks in the lug and lock set which they could order shows what appears to be a larger diameter and deeper cone than the 09599493 set.

 

These are from GM Part No. 17801711, which is a set of 20 lugs and 4 locks

The smaller ones are most likely M12x1.5 and not M14x1.5. Both sets I have are the same long style. I have black 20's that were an option on the Custom Trail Boss.

Interesting. Both pics I included in my last post were of 14 x 1.5 locks. When you say you have two sets, do either or both look like these?

 

And do your lug nuts looks like these? Chrome or black doesn't matter, just wondering about their profile.

 

Thank you for trying to help me here.

I have about 4 or 5 sets of just plain lug nuts I've bought off ebay between extras for my Silverado I used them on my 08 Avalanche that I had a set of these Grazen 20" wheels on. The locking lugs are both the tall ones with the 3 rings near the base.

9596070 is used on all aluminum wheels with the decorative nuts, 1500-3500 trucks (and many other GM vehicles).  22mm socket size, M14x1.5 thread.  The only wheels that use anything different are the steel wheels on 1500s and HDs.

I bought a set of the 09599493. Those are the ones with the three rings near the base. I screwed one down onto the lug that I took a nut off of to compare, and it seated way down into the wheel. I'm just concerned that it's not making contact with enough of the wheel to be 100% effective. Are those the ones that you used on your Avalanche?

I've seen the ones on your pic above. I just don't understand how they can fit given the big difference in profile between them and the lugnuts that you also pictured, which match the ones on my truck in size. And I'm not sure they would fit into the wheels given how big around they are. The cone looks to be the right size but I wonder what purpose the gap between the cone and the larger ring serves. I don't believe that ring would ride against the flat surface of the wheel after the cone is screwed down tight.

Now the 85105298 lugnuts look right, and appear to match the profile of the lugs on my truck. The diameter appears to be larger than the 09599493 locks, with a larger cone. Now if I could just find some locks that were the same size as those nuts.

 

Thanks for the help guys. I'll keep digging.

I have the 9599493 on my truck (and the one piece GM lugs as well).  We've installed hundreds, heck maybe thousands of the 9599493 over the years.  They are (were) the correct locks.  No need to keep overthinking this.  9599493 (and other GM locks of this style) are made by McGard.    

 

85105298 are the new design "Thatcham" locks that replaced 9599493.  85105298 has the production style look on the top half of the lock and uses a perimeter key setup on it.    

 

Not much more to "dig" here.  This is all straight from GM parts catalogs and the accessories catalogs.

I picked these up today. Even though I already have what I believe are the same locks, I got the whole package for a very good price.

      OCI, not when but why?

      By KARNUT · Posted

      But Grumpy I did show several subdivisions that had homes starting in the 170K range. If you bought a Townhouse or Condo you could go cheaper. Same with a car 3000 dollars in the 70s translates to around 20K today. There are several models at that price. You actually get more for the money. In the 70s I drove a 3000$ car bought a 28K home and made 4.50 per hour. Thank goodness for overtime. Today I could buy a 170K house drive a 20K car and make 25 dollars an hour operating the same machine today. The difference the house, car, machine would be better and have AC. And I wouldn’t be taxed on overtime. And statistically your wife works too. Easing the burden. I thought we agreed to disagree. I brought receipts earlier, showing examples. I think you’re more stubborn than me. I was done with this debate.

      Another 6.2L engine failure!

      By MASONV88888888 · Posted

      My 2025 Silverado 1500 had to receive a brand-new engine (long block) under warranty last month at only around 16,500 miles. Before the replacement, the truck repeatedly displayed "Engine Oil Level Low" warnings, even though the Oil Life Monitor still showed around 50% remaining after about 6,000 miles since my last oil change. After seeing the warning several times, I checked the dipstick with the engine cold, and the oil level was completely normal. The next day, the message escalated to "Add Engine Oil." At first, I assumed it was just a faulty oil level sensor, so I brought the truck to the dealership. After inspecting the engine, they found internal cylinder wall scoring and ultimately replaced the entire long block under warranty. Before this happened, I was planning to install a 4-inch lift and suspension upgrade on my truck. After needing a new engine at just 16,500 miles, I honestly don't see the point anymore. I also contacted GM to ask whether my vehicle qualified for a buyback, but I was informed that it does not at this time. Anyway, this experience has left me with serious concerns about the long-term reliability of this engine. I sincerely hope NHTSA expands the current investigation or recall to include 2025 model and performs a thorough inspection of affected vehicles. My biggest concern is that these engines may fail shortly after the powertrain warranty expires. If GM truly stands behind this engine, then at the very least, please consider extending the powertrain warranty to 10 years for affected owners. That would go a long way toward restoring customer confidence.

      Without exception but then I'm the odd duck, right? I know what goes into that test, how it is calculated and thus how to beat it. But EPA values are often not beaten by the general public and the government has in past years adjusted the means and methods to come to those values to more closely approximate "Joe Average".    The only real trick to beating that EPA average is don't drive like "Joe Average".    It's the same method you used to profit from "Economic Migration" and in doing so beat the 'stats'. But you, like me, are not "Joe Average".     The thing you don't seem to grasp is this "Purchasing Power Index" isn't forward looking. It doesn't predict what it going to be but looks backward and states what it was. They are not telling us what the THINK, they are telling us what they MEASURED. Example:    Wife says "I'm going to lose 40 pounds by Christmas". May she does, maybe she doesn't but the doctors office who weighed her when she made that statement and again at Christmas only REPORTS what the RESULT was. You and I can banter about what was possible and what aunt Tilly did till the cows come home but the result is the result. Arguing otherwise is.....irrational. That's all I'm saying. This isn't about:      What you are calling a 'Statistic' is a RESULT not a CALCUATION and as a result the RULE. Like gravity as a rule, it can not be broken.
