The last modification made to the signature, was a Helwig Bigwig rear sway bar, this mod has been very successful. It took about three hours to install. The truck should be unladen when installing (camper off).
In our case I went through about 5 pounds of rags also, due to thick undercoating everywhere in that area, not at all like the installs shown on Shadetree Mechanics etc. where everything is shiny and new.
I would advise anyone with handling problems to put one on....
The difference in handling is huge.
This truck had a front one from the factory, it will break the sway bar end links quite easily, go Dodge engineers !!!
