Yes, lots of people on the different forums are talking about it. Some suggest they could use the Mopar lift that is used for the Diesel version, but I would not take the chance. They also indicated that there is going to be a new part number for the Mopar lift once it is ready for the 4xe.
This was posted on 4xe forum on Facebook:
Andrea Hayes Do not let them install the lift the Mopar 4xe lift has been pulled and sent back for re-engineering. Here is an email I received regarding the Mopar lift, this is from my dealers parts Dept a couple days ago "The 2” lift kit is not currently available for order. The design for the 4xE was flawed and needs to be redesigned.
The part number is 77072522, but the redesign will be assigned a new part number. There is no ETA for the redesign." Your dealer simply does not know any better non of the current lifts can handle the weight of the 4xe as the GVWR is 6400lbs nearly 1000lbs more than a non 4xe Rubicon.
