A friend asked me the other day about swapping his front springs for new ones. His question he asked was do the front springs have to be installed a certain way? I told him there is a top and a bottom and the heavier one on the drivers side. But I guess he wants to know does the coil have to sit a certain way on the perches for ride height? There aren't any stops so I would guess no but can any of you answer his question for me??
