I have 2009 sport 5.7 hemi, non-adjust pedals. I don't have the vibration and I hope I don't get it. I removed the big metal body mount dampeners when I installed the nerf bars. I have the Luverne and they mount to the body mounts. Maybe there's more metal there now so it dampening the vibration even more or does a better job with the harmonic distortion?
