Truck has 1” coil spacer in the front and 1” block in the back. Nitto ridge grappler 285/75r18 went on before it left the dealership.
Vibration starts at 95km and by 110 is full on shaking. I have another set of factory 18” from my 16 3500 that never had a problem on it or my 18 2500 mega. I will give them a try first before I check anything else.
The aisin on my 16 was always in the right gear. The 68rfe in the 2500 was always upshifting too soon. The new 19 aisin is somewhere in between. Sometimes when I’m accelerating it doesn’t upshift with any symmetry. It’s all over the place. But it is quite and pulls like a moth€|^|*|*|*£||.

It's been a while, thought I'd bump this thread now that there are a lot of units on the road.

I'm considering swapping trucks before the end of the year, but am wary of a dealer trade to get what I want. I don't want a third shaking Ram.

Any more feedback?

Towing or not, up to 85 either way I get no vibes. Had over 1 ton in the bed on the highway still no vibe. Letís hope it stays that way!

My 19 is smooth like I'm driving on glass. Does not vibrate. The passenger seat has a very minor, and I mean minor, movement on the highway. Less than any vehicle I have driven, and not enough to be considered an issue. I would consider it natural for any vehicle rolling down a paved road to have some type of harmonic vibration. To see the top of the passenger seat move, I have to take my eye off the road and stare at the seat to notice it. Can't hear of feel it any other way. My guess is the new frame dampeners are doing their job. RAM got this one right.

By the way the only reason I actually checked for this, is because my 2013 RAM's passenger seat would vibrate enough at 70MPH to cause me to take my eye off the road, to see what is vibrating enough to distract me. I would have to adjust the vertical position of the passenger seat to minimize the issue.
