Removing Torsion Bars? and leaving them out?

Yes. It's a spring. In fact, that's exactly what it is and nothing more.

And, um, I don't know of a truck, dodge or otherwise, with torsion bars.

That said, same tricks apply to all springs. With the weight of the vehicle on them, slowly heat them bitches up to dull cherry red evenly along their length and let air cool. Control arm still located, but the spring is out of the equation. Then bag to your hearts content.

Figuring out how to heat them without getting squished when the car drops is up to you.

I guess the low rider crowd does things differently than they used to?
