Very incorrect.
The only limiting factor is the GVW Rating on the door sticker. You cannot legally change that rating. The limiting components are not just the springs, almost every other suspension related component is designed for the rated payload and articulation capabilities too.
Conversly, simply putting PW springs into a standard W2500 will not give the W2500 the articulation and off road capabilities of a PW either.
suspension-wise, the only difference between the power wagon and a regular 2500 is the longer, softer springs, the use of blue/yellow bilstein shocks, disconnecting front sway-bar, and the front radius arms are the Articu-Link variant.
