The Stage 1 kit and Stage 2 rear do go together well. We have our Pro1 kit we put together using these 2 Porterbuilt kits. We then include our Pro2 air management that uses dual VIAIR compressors, 4 gallon tank, AccuAir VU4 valve, etc..... The truck will sit fairly level with this system, of course depending on your wheel size and tire heights.
