This is why our 4x4 systems are better than the competitors. I love the g80. Great write up!

I don't believe the means of achieving a locked differential is what defines whether a rear end is a locking, LS or an open. The gears you speak of are just a different way of engaging the rear end and just as the clutch pack will "slip" when enough force is applied a gear will break. Ideally, clutch packs are not really meant to slip they are much better off either fully engaged or disengaged. But in an LS they can have a varied state of engagement which gives it the limited slip. I would classify the G80 as a true locking rear end beings that both wheels will rotate at the same speed and torque in all situations when the rear end is locked where as an LS will not, they are not meant to slip.

The manner of achieving the lock is irrelevant to how the unit acts when lock is achieved.

Clutch packs r always engaged......they "slip" slightly in a turn so that the two opposite axles can differentiate due to turning at different speeds in a turn. Again, clutch packs are always engaged, just slightly less in a turn. An automatic "locking" differential is engaged 99.99% of the time......one side will disengage only when in a tight turn. The gear "teeth" separate/unlock, on one side or the other, to allow the axles to differentiate.

The G80 is a hybrid limited slip that activates automatically. The clutch packs in the G80 are set up very tight......too tight to perform smoothly in a tight turn on dry pavement. Under most driving conditions the G80 is a "open" diff......smooth and invisible. Jack the rear end up and you'll see the wheels spin opposite directions from each other when one wheel is turned, just like any "open" diff.

When unequal wheel speed reaches a set point, the G80 mechanism engages the clutch packs. At that point the diff performs like a very tight limited slip. There are no teeth/gears that "lock/engage" in the G80 rather the mechanism engages the very tight clutch packs. Again, the G80 is a hybrid limited slip diff.....it can/will "slip", just not much due to being "set up" very tight. Unless the G80 is "ragged on" hard/frequently, especially on dry pavement, the clutch packs should last forever under normal driving conditions. After all, under normal driving conditions the G80 clutch packs are not engaged so there is zero, zip, nada clutch wear.

A true automatic locking diff will have teeth/gears that are meshed/locked together under most driving conditions (going straight) and disengage only in a turn. The teeth/gears re-mesh together once the speed of both axles becomes equal.

Mine was sticking "locked" this past winter. Changed the fluid and drove it to lock and unlock it a couple times and it works fine now.

I know it is older thread. Is G80 a strong built locker

 

[dirtwarrior]

Will all the eletronics connect correctly like antilock brakes etc to any year rear

I’m an outspoken critic of the G80. I very much dislike the engagement design and lack of lock up control in certain off-road environments. I’ll admit that it works well for most but it’s not for me.

If you swap in any rear differential other than the one that came with the truck you need to be prepared for at least some kind of fabrication.

I understand your needs and The G80 operated not in your best interest off road. For the street it will be more predictable.
