This is based on my experience with lifting my JK Wrangler.
Think of the axle as being hinged by the drive shaft. When you insert a spacer or larger springs the axle pushes down and slightly forward. The axle kept centered by the track bar. The track bar usually mounts to the driver's side of the axle, runs parallel to the axle and connects to the passenger side frame. So... when you install a lift without adusting the length (or adding a drop bracket) to the track bar, the axle will shift to the passenger side. If the track bar is lengthened, the axle will remain centered.
The guys at Rocky Road said they include the adjustable rear track bar with their GC 2.25 lifts, but not the Commander. They could not explain why. I'm assuming the rear suspension is set up the same.
I hope somebody with this lift can confirm if their axle had shifted. If so, I need to order the adjustable track bar.
