Just curious frank what will the drag link flip do to help?
A few questions for you:
1. Did you align your Jeep after the lift?
2. Do you have a programmer to recalibrate your Jeep for the larger tires?
3. Did you get the drag link flip kit?
do you have aftermarket wheels? if so, did you remove the temp washer they put on at the factory to hold the disk brake in place?
also check your calipers, you'll need someone in the jeep to press the brakes, see if the left side is hanging any.
since it's so new, take it to the dealer and have them checked
