These "MONSTERS" will destroy your truck, you will have a hard time keeping the truck in the road- will follow ruts!. This is some advise from a close friend that did this and he practically shook the dash out of his truck, they will loosen things that are not supposed to loosened. Again, like the previous post, I ain`t your Dad but after all the money you spend , you will have a "COOL" looking truck, but just have to park in the Home Depot parking lot against the street so people can just look. Try to find some one who has already done this, and if they will shoot straight with you, I think you might change your mind. Go with the 19. 5`s I`m done!
