I'm Not sure what the factory mounts are, but the ones I was looking at was poly I'm pretty sure.
My truck has a vibration between 60 and 70. I have noticed a "bounce" around 50 mph. Hadn' put much thought into it. New tires, fresh paved blacktop, kinda hard to figure which would be the cause. My gmc doesn't bounce but it's over double the size & probably weight as well. I do have to say I didnt notice it on my way home this evening. I wasn' really paying attention, and the fact I was running upper 80s low 90s. At that speed everything was shaking and vibrating which is to be expected. Other than that no bounce when braking.
