The biggest difference between the G86 and the G80 is the mechanical locking capability of the G80.

Both are considered "limited slip" diffs, both have clutch packs that provide power transfer to the axle with the highest traction.

The G80 has the ability to "lock" the left and right axles (using a centrifugal weight activated mechanism) if the limited slip clutches need additional help.
The G80 LSD clutches can get you out of a low traction situation, without the locker, if you don't spin a wheel.


The G86 is a high performance LSD. Because of the clutch action, the power is transfered "gently" to the wheel with the greatest traction, ideal for high hp applications.


The G80 uses a locking pawl to "hard" engage the wheel with the greatest traction, exposing the diff to a lot of stress.


The end result is the same, power is transferred to the wheel with the greatest traction, the mechanics are just a little different.
