I second rocknredrubi. Get you some JKS adjustable trackbars to go with this lift. It will recenter your axles and help minimize ESP intervention in turns and adds to vehicle stability. I added mine about 3 months after the lift went on, so I had experience with and without. They are worth it.

The JKS uses rubber bushings (like the stock bars) and thus don't require grease like the FT, and they do not squeak.
