vibration on highway - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I've got a bad pulsating / vibration on the highway around 65-75 (of course)

from what I can tell, its not the tires. it feels like its the whole truck pulsating, doesn't really shake the steering wheel or rattle the truck, but just pulsates. between 65-75 the pulsating gets faster with the increase in speed.

i've rotated the tires from to back and it didn't change at all.

truck is lowered 4.5" front and a flip kit in the rear.

any suggestions for what I can check?
