The shackle bolts used between the springs and hangers do not require a specific torque rating because tightening the shackle bolts too much will squeeze the shackle straps against the leaf springs, and the whole suspension system will bind and cause problems. The best thing to do when tightening down shackle bolts is to use lock nuts, tighten them until they are snug, then back them off 1/4 turn. The lock nuts of the part # APS1 will keep them from backing off.
