I understand it would be costly and it would be smarter to just buy a ZR2 but I’m Just curious… are ZR2 lockers compatible with other trims such as an LTZ?

Physically yes, but you won't have the factory integrated buttons for the E lockers. I believe the wiring is just power and ground though, so you would really only need to wire up a toggle switch for power. Been considering at least a rear one for mine.

Are there aftermarket companies that sell the parts or were you going to try to buy factory?

Looking at factory since I'm not aware of anyone making aftermarket e-lockers for these trucks yet.

Pretty sure they're the ones supplying them for the ZR2/AT4x. They supply the G80.

Any new ground on this? I've had good luck with my G80, would still like to lock up the front. Already have a lot of work done on my truck so I'd rather just upgrade it.

I would think it wouldn't be too hard, maybe expensive. Buy front ZR2 diff, wiring harness and dash switches and could probably make it look like it came from the factory with it. Bet it wouldn't be bad depending on price of items I listed

You can't just slap in parts anymore. EVERYTHING is controlled by the BCM(body control module). It would require programming which dealers WILL NOT DO! The locker itself should be actuated by just 12V+ and ground. I'm not sure how much current draw there is, so it would probably need to be wired up using a relay with heavy gauge wire and just an on off switch in the cab.

You should be able to easily bypass the BCM.  The BCM is only needed if you want to integrate it with current control knobs in your vehicle.  If it only needs a 12V power supply and a switch to activate it, you can run that directly from the battery, and back to the battery via an auxiliary switch.  I'll look up the wiring diagram and see what I can find.

Part Number 25 is the Electronic Locker.

So it basically looks like a power supply that runs to the differential, and then back to the Chassis Control Module to go to ground.  That appears to be a simple circuit you could wire directly from the battery, to a switch on your dash, and then to a local ground, bypassing any control module all together.

Upon my research I agree. Shouldn't be that bad at all

      Replacing 2.7L on 2021 Silverado with 2023 2.7L

      I’m definitely interested to hear the end result here.

      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.

      OCI, not when but why?

      By Grumpy Bear · Posted

      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.

      Rattle in the rear!

      By MASONV88888888 · Posted

      Just wanted to say thank you for posting this. Years later, your thread is still helping Silverado owners.   I bought my 2025 Silverado 1500 in January 2025, and I've had what feels like the exact same rattle since day one. After reading your findings, I believe my truck has the same issue with the cable carrier contacting the rear sliding window. To be honest, I had pretty much given up on pursuing the issue. It wasn't until I recently drove another brand's pickup that I realized just how quiet their cabin was—and how noisy mine has been all along. On my truck, the rattle happens on almost any paved road, gets even worse on rougher pavement, and I can even hear it during braking and acceleration.   I actually referenced your thread when submitting my case to GM, hoping they'll recognize this as a recurring issue instead of treating it as an isolated incident. The reason I reached out to GM first is because my dealership told me they would need to keep the truck for at least two days just to diagnose the problem. I was concerned that even after two days, they still might not be able to identify the source of the rattle before giving the truck back to me. I had also asked a few dealerships about this issue during previous service visits, but none of them seemed to know what was causing it or had a solution. That's why I decided to contact GM directly first, hoping they might already have an official repair procedure or guidance for this issue.   I also hope GM eventually comes up with an official fix for this problem. I have a feeling there are many Silverado owners experiencing the same rattle, but most either choose to live with it or simply don't know what the cause is.   Really appreciate you taking the time to document your diagnosis. Your post is still making a difference years later.
