    i never measured, but its a 99 with low air leaf susp. Its what most 379s come factory with. Not a heavy spec with anything extra.

    MY 2013, 388 Had a 6mm block in it and it sat up like a 4x4 dump truck lol I went to peterbilt and they had a .05mm block or basically a wedge and I had u bolts made locally cost me total with alignment $520.00 lowered front end 5.5 inches and had to adjust the rear bags a little to compensate the drive angle but has worked fine for a couple years now

    Did you have to raise or lower your rear bags? I’m in the same situation right now except mine was lowered like this when I bought it and leveling valve went bad before I could measure it.
