Thank you.

I have thought about spring rates. Ford in the USA wont tell me if there is different spring rates for my year. They keep telling me dealership in Norway should provide me this information. Problem is that there is only a few US trucks in Norway, and dealership cant give me any information.

I have searched for aftermarket springs with lower springrate, but cant find any.

As for tires, I cant change to P tires. Norwegian laws tell me I need LT tires.
