Aftermarket U-bolts for lift blocks are mostly the same size. Although, the general rule is you don't reuse U-bolts. The shackle is what the leaf pivots on. If the spring was attached to the frame at both ends with out a shackle on one end, there wouldn't be any cycling of the suspension in the rear because as you flatten out a part of the circle, the location of the points of attachment would have to move. The shackle accomplishes this by letting one end move back as the leaf flattens out. Lift blocks are cheaper, but it becomes easier to torque the axle with them, ie you could see wheel hop in some instances, cause premature failure of the U-joints, or even break a driveshaft. These are highly uncommon unless you are running high horsepower or high torque applications.
