Just how low can you get with a basic c knotch

[jadedbird]

Im planning on running a basic air ride system....
no seriously. really basic. so basic that if i need to add some air, ill have to run to the gas station or use a little pre-filer compressor. (i dont plan on playing with the ride height much)
I was wondering JUST how low can you go with a basic c knotch like the bolt in kits from cpp. i dont want to lay frame, but the 3/5 drop with 2" blocks just arent enough for me. so i was wondering if anyone has bagged their truck without dishing out the time and cash to modify the whole frame.
the front will be bagged on the stock a arms. yes i know they arent as flexible as the tubular aftermarkets.
