A word of caution on the luke's link - the outside diameter of the replacement link is pretty large. I had installed it on mine to find out when I hit a bump with the left tire the link would actually hit the differential cover. this is not typical on all 4x4's because of the location of the axle. When the alignments are done the front axle can be shifted forwards or backwards by the cam bolts. If the axle is too far forward the link will hit. So I took the link off and bought a moog track bar for $138. The lukes link I will keep to use on my other truck which, being a 1 ton dually, 2 wheel drive straight axle. And there is plenty of clearance.
