If you have spring suspension, there should be 3 holes in each shackle so you can adjust the spring height to help raise or lower the rig. Unless requested before production, DRV usually set the springs in the top hole which is the lowest setting for the rig height. Should be easy adn inexpensive for any trailer shop to raise the rig if that is the case.
