Well, to be fair, if you're feeling like your ride is sketchy at high speeds, you may just need to add a bit more positive caster and, if you haven't done so already, install a drag link flip/front track bar relocation kit. That should help out quite a bit and without an expensive upgrade. Long arms will correct your suspension geometry and improve the overall feel of your ride especially on pavement and when bombing through the desert. I would highly recommend the EVO long arm kit especially if you're willing to burn it in (can be bolted but welded is better). If you need your kit to be bolted on, I have run the Full Traction kit and it works well too.
