Will you derate one of your trailers?

Will you derate one of your trailers from 9,760 pounds to say 9,000 pounds?

In compliance with NHTSA rules, we cannot de-rate any trailer for which we have published standard ratings. NHTSA believes that de-rating points to regulation avoidance, such as trying to avoid a CDL license requirement, or brake requirements in some states. If you have a specific trailer need or application you can contact a Diamond C rep at 800-827-3512 to figure out what options you might have.
