Outer Limits 4x4 Board

im in the process of putting feroza rear springs in my sierra and im curious as to what the extra small leaves on the springs are for?

the short thick one on the bottom? Its a load leaf, so if you pack up the back heaps and are towing the springs will drop onto that one and will provide support for those heavy loads

nuh theres a pack of about 3 attached to one end of the spring. I'll try get some pics today and post them up
