U-Bolts Required: this rear block kit does not come standard with U-bolts, and cannot be used with the factory U-Bolts. Zone's optional U-bolts will only work if you're using this block in a stacked application with the stock block. If you're installing this block onto the axle by itself, you will need a set of 10" to 10.5" U-bolts for proper fitment.
