Hello, I am purchasing the 2025 Chevrolet 3500 LTZ dual wheel which has a towing capacity of +31K pounds. I add the Z6A option. But do you know if the equipment installed with the Z6A option can support at least 30K. Or it is only 25K or even 20K, Thanks.

Trailer Hitch Part Number: 84632891. But I can't find towing capacity.

 

Depends on what ball you put in the hitch. But the hitch itself will take whatever the trailering information label on the drivers door jamb says, plus more.

My previous 1/2 tons trucks had the Z71 package with the Z71 4x4 badge on the front fender. My current truck is an AT4 HD that has all of the Z71 or X31 stuff but no badging except for AT4.

The locker is standard on any and all HD. The "skid plates" is one tiny transfer case plate you can add yourself for less than $100. Better yet, add the ZR2 transfer case skid plate instead.

Multiple ways the factory spray liner is optioned.  Its a standalone option on HD trucks (rpo code CGN), it is part of the Z71 Off Road and Protection package, it is part of the Z6A Gooseneck package,

Z6A hitch supports whatever the highest tow rating GM has possible.  So a 2wd regular cab dually diesel with NHT max trailer which is rated for 36,000lbs 5th/goose, or a 4x4 high country dually gas which is rated for 17,600lbs 5th/goose, they use the same hitch.

 

That said, your tow ratings will be published in your driver's door jamb specific to your VIN.  It will have max rating for conventional towing and 5th wheel/gooseneck.

I’m glad GM has finally started putting hitches on that are rated for the same (or more) as the truck. The conventional hitch on my 2500 has a sticker saying it’s rated for 20k even though my truck is only 14.5k.
 

I recall my 2009 1500 was rated for 7500lbs but the factory hitch was only 6k so I had to replace it.

      Monday looks like a good day for the dealer to test an ac issue. Hopefully it all turns out good.

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By bluev8 · Posted

      That makes sense, and I think you are describing the real product problem. Capturing data is the easy part. If the owner or technician has to manually dig through five minutes of millisecond-level logs, the product has already failed. The device would be at the ECM harness, not at the OBD port, so I agree that data retrieval and event marking need to be thought through carefully. The way I am thinking about the architecture is: The recorder itself should not depend on a phone, app, Bluetooth, Wi-Fi, or cloud connection to capture the event. It should always keep a local rolling buffer and lock the event locally. A button, phone app, or small cabin device would only act as an event marker. If the driver feels a stumble and presses the button 10–30 seconds later, the pre-buffer has to already contain the useful data. For data retrieval, the practical options would be a sealed service USB lead, Wi-Fi download, or a phone/cabin companion device. I would not expect the owner to remove the ECM-side module or work with raw files directly. The cloud or AI side would be for interpretation, not for capturing the event. The truck may have no connection when the issue happens, so the evidence has to be saved locally first. After that, cloud processing could help decode the data, compare it against baselines, and generate a readable report. For the first version, I would keep the automatic triggers conservative and objective: driver event marker bus-off error passive voltage drop / brownout device reset FIFO or queue overflow a normally periodic message disappearing side-to-side communication mismatch, if the topology supports that For “learning normal,” I agree with your point, but I would not want to overclaim it as automatic root-cause diagnosis at first. A realistic first step would be learned baseline comparison for that specific vehicle and operating condition. For example, a value would only be compared against similar conditions: RPM range load / MAP throttle position gear / vehicle speed coolant and oil temperature battery voltage AFM/DFM state, if decoded and validated Then the report could flag things like: this periodic message disappeared compared with its normal timing this value deviated from this vehicle’s normal range under similar conditions the same abnormal pattern repeated after the same type of event the anomaly occurred together with voltage, oil-pressure, misfire, or communication changes But I would still call that “abnormal pattern detected,” not “replace this part,” unless there is enough validated repair data behind it. So the intended product would not be “here is a huge log.” It would need to be an event package: what triggered the capture how much pre/post data was preserved what changed before and after the event whether the device itself reset, overflowed, or saw a bus error selected graphs around the event raw data only as supporting evidence From your perspective, what would make this kind of report useful instead of just another datalog? For example: What are the top 5 parameters or events you would want highlighted first? Would you trust a learned baseline for that specific vehicle, or would you prefer fixed thresholds? How much false-positive flagging would be acceptable before you stopped looking at the reports? What would a one-page report need to show for an independent shop to take it seriously? For misfire, AFM/DFM, oil pressure, or U-code complaints, what would you want the tool to flag automatically?
