Ok so my truck has a horrible vibration between 63-65 to 70-72 does not happen before or after those speeds, any suggestions you can feel it through the hole truck.
Do you have aftermarket torsion keys on the truck?

Once I put my kit on I got that vibration and once in awhile I would get a bouncy feeling on the whole truck...I adjusted the keys and it took some of it out...It's annoying right? I know mine is....
