Differential covers

[Comandore3]

Hello colleges !
I would like to put on my 2021 Rubicon 2 door ARB differential covers (front and back). So I would like to find out what kind of axels my Jeep have ?
Kindest regards!

Here's what I ordered, and have not yet installed, so...no guarantees:

ARB M210 Red Front Diff Cover
Front M210 Diff Cover gasket Mopar part number 68400380AA

ARB M220 Red Differential Cover
Rear M220 Diff Cover gasket Mopar Part Number 68401298AA

Royal Purple 75W-90 Synthetic Gear Oil - 4 quarts.

Torque Wrench (foot pounds...not inch pounds...)

Get you some brake cleaner, and watch a few videos on YouTube if you've never done it before.

Thank you!

You won't need new gaskets because what is on there now is reusable.

Run your VIN and check your build sheet for axle specs.

What are the torque specs? Can't find anywhere. Are all diff covers the same or are aftermarket different for torque?
