I have a 1984 4runner. The previous owner installed 4 inch lift blocks in the rear and 1.5 inch shackle lift up front with 35x15.50 Mickey claws. Obviously the front rubs... I want a 4 inch lift but at the moment don't have the cash. I noticed the front leafs are arched upwards. Would it be logical to take them apart and flip it so the arch is down, just as a temporary fix. I have seen this done to lower cars and trucks but am not sure of lifting it. Any input is greatly appreciated.
