Addco told me early this year that the 5th Gen 4Runner sway bars were being built. They had built one (rear), but had not produced it yet. It would be just a couple more weeks. Call them back. I called them back about a half dozen times every 2-4 weeks. Finally, they told me (late summer) that they would give me a call when they have them. Still waiting for that call......
I have Bilsteins (actually Bilsteins and springs from FJ Trail Team) and I have BFG AT's, definite improvement, but still looking for more sway control. I could go to a heavier spring, but don't want to lift it much.
