My truck is leveled with bilisteins at 2.5 in the front. The boat is a 1975 glastron that i have no ideal the weight of. The trailer is a 20ft double axle i think 3200 pound axles. I have a adjustable hitch to level out what ever i end up towing. I really havent towed anything over the capacity, but for some reason the back of the truck drops low enough i cant see over my hood very good while driving. It also bounces like a Cadillac.

 

Yup, the leveling kit is making it drag rear when you use it as a truck. There is a reason why pickups come with the rear higher than the front.

 

Well installed the Air Bags earlier and now the resonation is completely gone and the vibration is 60-70% gone. So now im going to take it 1 more time to Discount and have them do another balance. The ride is so much more controllable and handles better like my 2003 1500. And fyi at 30psi it did lift my rear about 1 in, then i lowered the pressure to 15psi, And it went back to about level.

 

Drove the 30 mile trip to work this morning and definently smoother than it was and no resonating, now to see if it will be easier to figure what tire or rim is unbalanced.

 

I have two sets of rims for my 09, 20x9s american eagles, and moto metal, each has its own set of completely different tires, never a vibration issue until 85mph plus...(i live in the desert)...and and it is always a balance issue, freshly balanced, no issues, if i go off road once, I get the hi speed shimmy again.Hard to find a good , knowledgeable tire guy nowadays as well, especially in the big chain stores.A few years back had 305 50 20s on, they were nothing but a headache,I ripped them off in less then 7k and they are rotting in my pump house now.275 65 20 works great for me!

 

Yea sounds about right, im going back one more time today because i drive to the coast for a week next monday and i didnt want to feel that vibration the whole way. I do have to say that since i squeezed the airbags into the coils it rides so much better and stiffer now. Im gonna invest in some stabalizers for the front next.
