After putting ajustable Bilsteins and load range E tires on my truck the vibes went away maybe 80% of the time. So then I started messing with air pressure on the tires. They are a good sized all terrain tire with max pressure of 80psi. I originally had them set at 50. Now I dropped them to 40psi and it rides very well. Much better than stock and vibe is 99% gone. Only time I feel it slightly is when going up or down inclines overpasses etc. Don't know if this helps anyone but thought I'd chime in
