Wait… M210…M220 Axles…WHAT????
Now when we talk about the new M210 and M220 axles under the 2018+ JL, we are talking about the “NEW” Advantek Dana 44s from Dana-Spicer. They are new, they are stronger and they are quite a bit different from the JK D44s used in the last generation of Wranglers (2007-20018 JK/JKUs). Dana is using their metric dimensions as model designators, so the front Dana 44 Advantek has a 210mm dia. ring gear and the rear Dana 44 Advantek has a 220mm ring gear.
