For some odd reason my little 4.3 doesn't have differential code. I've assumed this truck might have a G80 differential but boy was I wrong! Check my pic to let me know what differntial i might have. I edited the last digits of my vin for security reasons.

Weird, my 3.23's have a G80, wonder if that came with the towing package.

 

Yes, GM did included the G80 Eaton locker with the tow package

 

I have the G80 locker in my 2011 with 3.23's and I don't have the tow package, Actually my trucks only options were Those big tow mirrors, G80 and the better cloth seats. Otherwise it;s just has the base W/T package.

"GU5" = 3.23:1 non locking rear end gear.

 

You also do not have an "LSD".

Yeah I decoded his PRO codes and yep he has the standard open diff. with 3.23 gears.

 

I have both GU5 and G80 for my PRO codes on my 2011 along with the standard Z83 suspension or "Smooth Ride" as GM calls it.

Installed in your vehicles rear end, the "G80" RPO would indicate a locker, or locking device, that would spin both wheels @ the same rpm.

 

On Sara (2001 Z28) the "G80" RPO code indicated a Zexel Torson LSD.

      The Peckish Synapse

      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.
