I extended my rear sway links 2 inches (2" rear, 2.5 front lift) i drove a while with them stock but it made a huge difference extending them. Front is still stock. I drove over a year and a half before i got and adjustable trac bar and I couldnt really tell a difference driving. I just wanted to make it right. I have new isolators in the basement and just have't put them in. Wish I had done it when I did the lift.
