I just bought an '07 Ram1500 Thunder Road 4x2, I was looking underneath it and discovered that there are matching weights on both sides that look like cast iron doughnuts attached to the frame. Also in the back, up behind the bumper is a long round cast iron piece that is mounted on rubber bushings that will twist back and forth. I am baffled. Any ideas? Thanks in advance!

Maybe the Hemi is so powerful they have to weight the truck down?...

That's weird! If you can, post some pics for us non 07's.

 

Here they are...

It's a bomb! .. just kidding, I have no idea what it is, but I don't have anything like that on my '07 Sport QC.

 

Bomb! LOL. I was thinking the same thing.
Dublea, are there any wires or sensors coming from anywhere? What does the lettering say on the "doughnut" shaped one? Are the different pieces related or attached somehow? If there are no wires, no mechanical propertiesor anything like that I would consider them dead weight and fire up the plasma cutter.

 

I have them on the frame of my 06 as well. Best answer I've heard from other forums is that they're used to dissipate vibration in the frame. Mine must not be cast iron though, or they were painted, because they've always looked silver.

 

Well, I guess that makes sense. Vibration dampening. I wish mine were not already rusting......

 

Well it appears that it's a Hemi only thing... we were at a Dodge dealership looking at other cars and I looked under some of the Ram 1500's and they are only on the Hemi's.

 

Mine are not rusting but my rear bumper is.

 

This would be a good one for Dr. Z
