alowerlevel, as mentioned in my earlier post, the frame has been narrowed and notched. I narrowed it 2 1/2" per side and then notched it 1". Probably sounds redundant, but I only narrowed it 2 1/2" because I wanted to have enough room for the mufflers and I wasn't sure if the stock lower suspension/arms would function properly if I moved it in more than 2 1/2". Looking back, I think it would work ok, but it doesn't leave much room for the mufflers in the stock location.
