BACKRACK is one of the most prolific producers of Headache Racks. They have the widest range of fully customisable racks that are perfect for work or play, and are engineered to last a long time. Also known as Cab Guards, they are engineered to protect your cab from damage caused by shifting cargo and hauling long cargo like ladders or lumber. They can be paired with Rear Racks to create full bed Truck Racks.
There are other brands that manufacture high quality headache racks as well, although without as many options. Some examples are the Aries AdvantEDGE, Elite Full Mesh Cab Guard, and the WestCan Standard Cab Guard.
