Used, but excellent condition. Has been installed, so there are a few small signs of having been installed. Everything looks great when installed. Everything original is there, except for the air fittings, which you’ll have to get the correct ones for your application anyway. A couple of wires (for tying into vehicle wiring) on the harness are shorter than original, but still plenty long enough for most applications. E-level+ ECU & wire harness & pressure sensor (for your air tank pressure & control of your compressor). VU4 valve block & wire harness. Pressure upgrade (4 pressure sensors and wire harness). All original paperwork/ installation instructions. Feel free to ask any questions.
