Necessary? Probably not, but I definitely advise it. First you'll need an adjustable trackbar to recenter your front axle after the lift. Second, the increased stress of heavier tires COULD contribute to wallowing out the trackbar mounting holes. My opinion best way to prevent that is with a beefy Trackbar and swapping hardware from 14mm stock bolts to Grade 8 9/16" bolts. Best deal is just to do the full Northridge4x4 bolt upgrade when you do the lift. That's what I did. It might add 30-45 minutes to your install but the piece of mind was worth it to me.
