I'm not an expert, but lowering it 1" wouldn't you need a front end alignment?
dont think so in this case. If you adjust the torsion bars, you might. I did my own alignment in the garage
last month, after I replaced ball joints. Taped a flaslight to a pole, then pressed pole against front tire, until
light was pointing straight ahead, when making adjustments to tie rods. I then went out and drove it, seeing no pull,
then came back and checked tire temps with a temp gun, across the tire. Before I made adjustments, tire temps
were about 10 degrees higher on one side of tread compared to other, which meant out of alignment.
