Anyone boxed the frame of an OBS?

I hate the way the frame twists up. I know this is by design but it drives me crazy to see the thing twist up.

Has anyone boxed their frame? What kind of results did you see?

where omn the frame do you want boxed.

If it was feasible the whole dern thing.

I once talked to a custom spring manufacturer in So Cali and they had built a couple extreme lifted OBS trucks. They said that boxing the frame made them ride significantly better because it made the springs do the work of dampening the ride, instead of the whole truck. You are right though, the truck frame was designed to twist with the rough roads, particularly the crew trucks. The frame was used for the needed articulation.

do u have any pics on this?
