Good luck, of I were you I'd add them ASAP, oh yeah I did.
Pinion shudder. OK, thanks. I've been looking for that definition for a long time and glad someone mentioned a logical name for the problem. I googled it to verify and found some good info about it.
The 1500 series trucks of today, especially the Gen 4 Ram models, are more like a really big SUV. They are purposed for just everyday runaround and hauling light loads. They are also very capable TT pullers if one knows how to select the correct trailer and mods/additions.
The biggest problem with the Ram 1500 is that it is way overpowered for everyday use (not hauling). If you are sitting still and slam the throttle to the floor you will be introduced to some aggressive "wheel hopping". It's even worse on wet pavement. Sometimes it feels like the rear wheels are actually jumping off the pavement. But they are getting light enough during the "hop" that you will hear multiple quick tire squeals.
When I installed the airbags I noticed a significant reduction in hopping when set to 5 psi. At 12 psi the problem completely disappears. Obviously, the airbags have done a good job of stabilizing the rear end. Seeing the operation of the bags agrees with some technical articles I read regarding pinion shudder.
Add the airbags, E-load tires and a Class V hitch (attach points on the Class V extend further forward than a Class IV) and now you have a pretty good tow vehicle.
I'm not sure about the 2500/3500 trucks (or even other brands) but I think they have at least some of the same problem. I also have them on my 2500 Ram CTD and they really smooth things out.
