I'm new to the Jeep world so please don't lose patience with me, I'm looking for advice from real/honest/experienced people. I was at a local 4x4 mod shop (Desert Rat) and the sales guy told me that AEV lifts are the best lift out there to prevent the death wobble. He told me that lifts change the geometry of the front diff. He told me that the AEV lift is specifically designed for the JK's and is the safest way to go. The AEV's are pretty expensive and I am wondering if this guy is just trying to make an extra buck????
