With the extra height from a suspension lift, there will be some extra forces flowing through the sway bar links which affix each end of the swaybar to the spindle on the wheel hub. And there are reports of many factory fitted links snapping under this pressure, so you should consider upgrading.
Given the extra forces that flow through your vehicle after a suspension lift, and the dangerous affect this can have on your swaybar links, it's a smart move to think about installing heavy duty performance swaybar links.
You may hear of drivers removing their swaybars to enhance their drive experience, but be warned this is illegal and very unsafe... because it negatively affects vehicle handling and safety.
