I have a 2020 Silverado HC 1500 with the 6.2L and, I think it has the 9.76 rear end.  I am considering, at least, adding a rear locker.  I'd like to use a factory option locker, has anyone done this and have some insight into the process?

High Country has the rear G80 locker as standard equipment.

Not truly a locker. It's a mechanical limited slip. It doesn't work above 35mph.

Is there an actual Locker that has been offered in our trucks?

The ZR2 is the only truck with an electronic locker front and rear. So far nobody has been able to figure out if it is possible to retrofit into other trucks.

it's a locker, just needs ~100 rpm difference in wheel speed between the wheels and it locks in, disengages on it's own also...likely when the wheels stop and unloaded it pops out?, I forget the parameters when it will disengage, it operates automatically, I'd definitely look at a manual e-locker(zr2) or the true-trac limited slip as preference to the g80 (all of them are eaton), but you at least have a locker that will likely only engage when you actually need it so it's not a terrible option, I would take the g80 over any of the conventional clutch pack type mechanical slip differentials, the only one of those worth having is the true-trac(no clutch plates to service all the time), a lunchbox locker would also be something I'd consider so if anyone knows what will fit these trucks any info appreciated

On 2022 1500 WT and Custom the G80 rear locker is an available option

On all other 2022 1500 LTD Silverado trims the G80 is standard. 

Refreshed 2022 ZR2 gets the front and rear E-lockers, other trims above WT and Custom get the G80.

 

Similar with the Sierra 

AT4X gets the G93 and G94

Pro trims have available G80

All other trims G80 rear is standard

 

 

9.76" appears to be on NHT only

Incorrect, it is a true locker.  It works just fine above 35 MPH, hell I've been locked at 70MPH, it just has to initially engage below 35 mph.  If you lock it up at 5 mph then it will stay locked, regardless of your speed, until you do a significant turn maneuver which releases the armature.  When it locks, it is a 100 % locked, mechanical engagement and it will not slip.  I'm not sure where you got your information from, but it isn't accurate.

      It varies a ton around me. Some places are still at $5.00 or higher and others are way down into the $4's.   Offroad diesel was $4.02 at the one station I passed today.

      2027 Chevrolet Silverado: Official Discussion

      By Hdwrguy · Posted

      So after reading the reveal from Chevrolet, I kept asking myself...why did the trim levels change?   Here are the official ones:   Work Truck (WT): The quintessential fleet truck, built with durable, easy-to-clean interiors for commercial or utilitarian use. Custom: A stylish, road-oriented trim that adds a more refined appearance, standard dual exhaust, and modern exterior styling. Custom Trail Boss: An entry-level off-roader featuring a 2-inch factory suspension lift and 34-inch mud-terrain tires on a budget. Silverado: Serving as the new base consumer truck (replacing the previous LT trim), it comes standard with the Z71 off-road package when equipped with 4WD. Trail Boss: Steps up the off-road hardware with the 2-inch lift, 34-inch tires, monotube shocks, an exclusive off-road hood, and more premium interior options. ZR2: The flagship off-roader. It boasts 35-inch mud-terrain tires, Multimatic DSSV dampers, front and rear electronic lockers, forged carbon-fiber interior accents, and an available hardcore Bison Edition (co-developed with AEV). High Country: The pinnacle of luxury. It replaces bright chrome with modern satin chrome, 22-inch wheels, premium leather, real wood interior trim, a panoramic sunroof, and an exclusive front-passenger touchscreen. As others have stated, why would you want a Silverado - 'Silverado' - wth?? LT needs to remain!!!   Also, there will no longer be a dedicated Z71 model.  All 4x4 trucks will have the Z71 package. Carplay is also something that cannot be removed.  Hopefully it will remain.     I am excited about the 5.7L V8 (350 C.I.D.)  Old school Chevy power.  My only concern is whatever version of AFM/DFM cylinder deactivation.  Too bad that isn't an option a buyer can choose to have or not.   I will definitely be stopping by my local dealership when these trucks start showing up.

      OCI, not when but why?

      By Chuck FB · Posted

      The not as clean as one would assume theme with the new engine oil, that reminds me of comments over the years with mechanics not always being so on board with filling an oil filter, not from the center anyway due to that typically being the clean side of the filter, danger of some contaminant falling into the filter if not careful but the realization now that the oil may not be as pure as one had assumed it would surely be. Yes it would be possible to fill from the small holes but that means messing with something to prop open the anti drain back valve if the filter is so equipped and not damage that valve in the process. Me, I have hardly ever prefilled an engine oil filter however I have prefilled diesel fuel filters with a filter on a fuel bulk tank and for anyone that has messed with diesel engines with filters and units that have a limited or no way of priming them, putting on a dry filter is a bad day to say the least with those crappy systems. But anyway back to not so clean engine oil, indeed perhaps its not so bad after all that I have not made a practice of prefilling oil filters.    As Grumpy Bear commented on keeping things clean, that I really have to wonder what the typical practice is at a dealer or any other shop that changes engine oil, do they make sure to wipe or wash off the oil plug and certainly if it fell into some gunk or onto a dirty floor, or that they wiped the filter mounting flange and didn't go and use some dirty rag and end up adding dirt to the inside of the head of the filter mount. Or be careless in how they stored or handled the new filter and if they were bumping into items under the vehicle with the filter opening facing up and having dirt drop right into the filter and if so right into the threaded center that is on the clean side. The top side, did they clean away the built up gunk that may be around the filler before removing the cap or to be really careful at that point that something right close to the filler hole that was hidden under the caps flange won't fall into the engine. Or did they clean the funnel or was that just laying there covered in oil from the oil change before and dust kicked up from sweeping the floor stuck to the oil and now that will go running into the next persons engine due to just not cleaning the funnel as "they won't know anyway" attitude as that young guy is more worried about taking a break so he can go outside and smoke a joint. Just random points that came to mind when I think about what some hired personnel may do that the shop foreman has no idea of or perhaps the whole attitude of some shops may be "eh ... who cares, they will never know the difference anyway".
