Bassicly with these ram trucks , when people refer to laying full frame, they mean laying the truck out flat on the frame front to back, which will require Zing the frame.
If you were to just bag the truck, without the Z, the truck lays with the rear lower than the front, and looks odd.
True frame means, laying full frame front to back.
Its a big jump from going to 22s to 24s on one of these labor wise, the parts used would still be close to the same, but labor wise you will need to tub the firewall, narrow the rear end. With 22s you can usually get away without doing that.
I sell a full line of parts to lay out an 06-08 ram, everything you could possibly need. If you need some info or prices shoot me an email
