There are 3 (or 4?) rear axles possible on our trucks.

Fully open 3.42 - available on V6 & Diesel
G80 Locking Diff 3.42 - available on V6 & Diesel, required for tow package, standard on Z71. (the availability differed on the Canyon, but it was required for the tow package, standard on the All Terrain.)

Fully Open 4.10 - 4 cyl gasser standard
G80 locker 4.10 - I believe this was also available with the 4 cyl gasser, but tow package not available with 4 cyl gasser. Not sure if there were any other conditions required to get the G80 with the 4 cyl gasser.

I forget, was it Dana or Eaton that made these differentials?

Our rear axle is a Dana M220, sometimes referred to as a Dana 46 (which is different than the actual Dana 46 on Dana's website) since it's supposedly a little bigger/stronger than a Dana 44. The new Jeep Wrangler JL uses the Dana M220 rear on some trims as well, however I've seen no confirmation that there is any parts interchangeability between the Jeep and GM implementations. They could have mfr-specific changes that mean we can't take advantage of the aftermarket parts that become available for the Jeep axles.

G80 is the RPO for the locker, it's not the axle model.

Hope this helps!
