AT4X ZR2 Front and Rear E-Locker Retrofit

[Gray_AT4]

I'm sure many of us have already considered it, does anyone have an idea as to how difficult the job would be?  I personally would love to retrofit at least the rear e-locker to my AT4.  The AT4X factory rock sliders and upgraded skid plates might also be worth a look.

I am willing to bet it is pretty damn difficult if not impossible. But nobody will know for sure until someone releases wiring schematics

I think it will be possible, but I don't think it'll be cheap. I'd like to re-gear as well down the road so that will help justify the cost.

 

If the aftermarket catches up on some lockers I think it will be way more reasonable price wise.

Eh. I bet the axles are the same as the regular half tons. Remains to be seen if they are AAM Co or actual GM units. 
Either way they should bolt right into the regular trucks. The locking diffs themselves should swap into your stock axles too. Assuming they’re using the stock axles. 
 

Wiring it all will be harder depending on what you want the finished result to look like.

I wouldn't be surprised if some things like the skid plates end up in the GM Performance Catalog as accessories everybody else can buy.  With the ZR2 and AT4X coming, don't be surprised if there are more goodies coming.  It happened to the ZR2 Colorado, and I'm not talking about just the Bison pieces.

Still keeping this in mind long term -- love the idea of a push button locker.

Has anyone been able to find anything new regarding this? I’ve been searching around for details regarding the axles used in the AT4X/ZR2’s and haven’t come up with anything.

Just install aftermarket lockers. Controls would be different, but functionality would be the same.

Name one that bolts into the 9.5” 12 bolt.

Nope. You’re right. No options. Too bad.

I've researched part numbers for the suspensions and drivetrains of the Z71 vs ZR2, and while some are the same, many are different, including the CV's.  It shouldn't be hard to retrofit the front locker if your willing to invest in the additional drivetrain components, you would most likely have to control it directly instead of going through the CAN system of the vehicle.  I'll wait and let somebody else try it first though, I'm fine with that I have.....for now.

It certainly wasn't going to use the stock CV's from the trucks. I bet the pumpkin is different too as it was on the few others that offered a locker in an IFS, they had to go cast iron if I recall. The amount of stress put on those at full drop, wheel turned with all the traction on it is insane and why very few have ever offered an IFS front locker, it is just asking for trouble. 

 

I don't understand the front locker in pick up trucks, the situation these vehicles would have to be in to make use of it is something 99.97% of full size owners will never see and 98.5% of midsize owners, and if they are you are probably in the wrong vehicle. Which is why in my other thread stated an electronic braked based traction system is far more useful. A front locker just eliminates that slight pause while the traction systems figures out, stops the spin and transfers power. A rear locker combined with that is a pretty unstoppable combo and far less prone to breaking.
