Pulled the trigger on Eaton lockers and more to do’s
Well Gents, About to enter a giant rabbit hole. Fixing to remove the diff carriers off of my ‘94 80 with 174k miles on the odo. I’ll drop them off at Zuk’s for install sometime this month (I hope) where he will also instal 4.88s. My steering knuckles aren’t leaking but since I need to remove...

x2. They're on my wishlist. Right in front of the SC.

I have Eatons in my 200 and ARB in my 80.
Either are fine, but I lean toward the Eatons. Not because I have any issue with my ARBs, but I trust people more experienced than me. The guy that built my diffs (Zuk) won't even install ARBs anymore due to callbacks and seal issues.

I have ARB in the rear only, never any problems, but I'd probably to Eaton up front if I add one...I think the electric is probably more reliable than the air in the end.

TJM ProLocker
TJM... I have ARB because the TJM's were back logged out so far they were unattainable and the ARB's came as a package deal with the gears. I would still prefer TJM lockers. I think they have a superior design that is easier to maintain.
Keiser, been running then for years front and rear. No fuss no muss.

I’m an arb guy. I they lock quickly, I can lock them pretty much at any reasonable speed, and if they’re set up well they’re pretty trouble free
Sorry to tell you, but it looks like they're gone, possibly for good. Manufacturing issues.
My ideal locker for the 80 series doesn't exist. What I'd like is a selectable electronic locking rear diff that acts as a limited slip diff when unlocked, not open. Designs like this do exist for some other vehicles, see here for example:

That's my ideal for the rear of the 80. In lieu of that, a Harrop elocker is my pick.
Select-A-Loc Ltd Slip to Lock - Auburn Gear Aftermarket
LIMITED SLIP DIFFERENTIAL TO FULL-LOCK. Select-A-Loc™ locks the axle shafts to the diff housing to transfer torque directly from the case.

My cheap ass has a Spartan in the rear as a placeholder until I decide the long term on this rig (but I only tend to keep mine for a 1-2 year period. “This one is a keeper” has been said many times)
Aftermarket lockers are expensive enough to warrant long term ownership as a rationale to spend $$ on a quality locker. Otherwise, ROI is tricky in today’s market with mods.

Had purchased a Spartan, which proved to be an issue installing (pin wouldn’t fit my carrier). Replaced that with a Yukon Grizzly, which I’ve been very pleased with. It’s an auto locker, and not a selectable though. Daily driving you can’t even tell it’s there.

Dang! Wish I put my last tax return into a set when I had a chance.
2nd would be Eaton Elockers, but the price difference probably means ARBs would bump Eatons into 3rd
i had a lokka, similar design to the spartan or grizzly, and i liked it. easy install, no real noticeable difference driving on the road other than the occasional clunk when shifting from p-d or r-d quickly. it could get a little squirrely on packed snow and ice but its easier to just adjust your driving style for the conditions and coast through your turns.
what you are describing is a Kaiser. The Keiser is always locked until there is a rotational difference between the wheels on that axle and then allows the faster tuning wheel to match the speed of the slower turning wheel.My ideal locker for the 80 series doesn't exist.

They don't seem to list one for 80 series rear?
Looked into it, and it's not what I'm thinking of. That design seems like it'd have problems when turning, directing excessive torque to the wheel with the slower rotation. Basically, 100% of the torque goes to the slowest turning wheel, unless the wheels are turning at the same speed, in which case it's a 50/50 split. This increases the likelihood of wheel slip on tarmac. It also could be quite noisy/unpredictable, as torque slams back and forth from side to side.
What I'm describing above with the select-a-loc design is a more traditional limited slip diff, with a typical open diff spider gear design, with a clutch pack included to add the limited slip functionality. Basically what was in the rear diff of my 80 series when it was made. Now, on top of that, add some locking dowels with an electromagnet, like the Harrop/Eaton design, to add a selectable locker feature. Best of both worlds, no compromises. Limited slip diff is better than open diff on road. Selectable locker is better than pure limited slip or open diff off road, but the limited slip helps you possibly avoid needing to lock in simple cases too. Auto lockers are a compromise both on and off road. This select-a-loc design beats everything else I've seen/can imagine. Unfortunately, not available for the 80 rear right now.
^^not quite but almost.... if youre not on the throttle in a corner it will act like an open diff, but the switch between open then locked can be concerning on the ice for the inexperienced....
and an auto locker doesnt have any compromises offroad, imho, seamless, and you can actually turn for the most part if locked in the front when you let off the gas
For reference i have eatons/detroit auto lockers in both front and back and they are the tits
But yes the LS and locker could be better
