Have a 2013 4dr Rubicon. Looking at ordering the 4.5 AEV SC lift with 37" tires. The AEV website states you do not need to upgrade your drive shaft with their lift, along with the shop that will be doing the work for me. When I was researching lifts, almost every source stated that a new drive shaft is required(1310). Can anyone answer this question for me. Thanks in advance!
