You may have heard truck back racks called many different names from back racks, cab guards and headache racks. Now you’re thinking why are they called headache racks?
There are two different theories on how truck back racks became headache racks.
The first theory for how truck back racks got their name is they prevent headaches from an accident. Headache racks protect the window preventing tools and equipment from breaking through. Also, they secure the shifting cargo in your box using bungee cords and ratchet straps.
The second theory for the name headache racks is truck owners being unaware while in the bed of their truck. In turn, smacking their head off the bottom beam causing a headache.
