there is a bolt on each side that holds all the springs together you will have to get a new one that is shorter cuz the stock one has a shoulder on it, other than that you just take off the u-bolts, then loosen the one in the middle that holds the leafs together and then drop the overload and use the new bolt to hold the 2 springs together that are left, put the u-bolts back on and drive it and make sure everything is good.
