TIRES AND TOWING


Recommended Posts

Posted

I drive a 2004 8.1 cc 2500hd, I pull a 12500lb 5th wheel, and was wondering if anyone else is towing this amount of weight with the torsion bars turned up and some 285/75/16 BFG's TA. I have the 3.73 gearing, volant intake, flowmaster, and westers. Wondering if I should switch rear end gears to the 4.10 so I dont lose any towing power? Also wondering what oil people use in this engine? I use the penzoil 5/30w, she use a little oil about every thousand miles of towing, but Ive heard this is normal? truck has 5000 miles on it. Any suggestions are appreciated. Thanks

4.10's would help you pull a load like that one...

 

I hope your 285's have a load range high enough to handle the load or the truck will be unstable and possibly dangerous to drive when towing.

 

Most 8.1L owners seem to use about a quart of oil in between changes.

The weight will be okay, the limit is 200lbs higher per tire on the 285's, becfause they are bigger. I just dont want to lose to much power. Anyone know how much the 4.10 gears would cost to change?

I think for a 4x4 they are around $1100-$1200.

 

Shotgun who is one of our members did the switch to 4.56's on his truck with the 6.0L to help with his big tires and his towing capabillities.

    • Correct.  2019-2021 model years are serviced by a different p/n.  19420611.  Recall 2021s use 19420611.   The recall engines 2022-2024 model years are serviced with 12740076.     The difference between 19420611 and 12740076 is GM changed injector size for 2022.  The injectors are smaller on 12740076 with smaller injector bores in the cylinder heads to match the smaller injectors.  So you can't install a 19420611 in a 2022-2024, and you can't install a 12740076 in a 2019-2021.     Both engines are the replacement engine p/ns that are in the L87 recall.  So both of these are the updated engines.     Here's a version of the L87 recall with the p/ns for all the parts needed.    RCRIT-25V274-7075.pdf   Note it shows 19420611 and 12740076 with an asterisk to a footnote "Use the VIN and the GM Electronic Parts Catalog (EPC) to determine which part to order if two or more part numbers are listed for the same part, as it may vary by vehicle options."    
    • Looking for advice from this group. Took my flawless 2020 6.2 TB to an unnamed shop for routine rear brakes and oil change. Tech forgot to put oil back in after the full service and needles to say, destroyed my engine.  It’s all on their shop video so they are responsible.   I had my Chevy dealer do the analysis and they confirmed its compromised and said engine replacement. The manager said they only get GM reman engines from GM with full 3 yr warranty and the one they would put in is not same as what’s they are swapping out on 21-25 for recall.    I am looking for advice why that would be a different engine because obviously I had the good 6.2 year and replacing it has my concerns with that recall for 21-15   Also what’s the pros and cons of accepting the engine swap vs telling the shop that bricked the truck to pay up so I buy a new truck. I’m concerned about stigma resale eventually if I just decide to get rid of it after the swap or other issues showing up after the swap out.  
    • Just looked up my records.  I've never gone over 5000 miles between oil changes.  At 46K miles, I have 10 oil changes.  I hope that will help.  I also installed the disabler last year.  I've still had a few times when it didn't seem to engage (which I can tell because the start stop feature kicks in), but for the most part, I think it's working.  For some reason, GM did not include the number of cylinders running in the information screen like I had on other models.  In my Cadillac, it shows me when it's running on 4 cylinders on the fuel milage screen.  I can't find that on my '21 Denali.
    • you might read through the info on gmupfitter.com for your truck, to find a good power source.
    • Melling I believe is/was the OEM on the lifters who explored this problem some years ago. The white paper they generated on the topic indicated two items of note when I read it. 1.) They only fail on the switch. Prevent the switch, prevent the failure. 2.) The majority fail due to deposits messing up the timing of that switch. Anyway that's what I got from it.    Mine have always been active, 195K+ now, and my oil maintenance is surgically clean.    Of course this assumes good parts. That is no heat treat issue or machining flaws. I get comfortable that these issues are in the rearview mirror by about 30K. IMHO naturally.
