58 1/2" Black Steel Innerside Truck Box

Steel Innersides utilize the same Gear-Lock™ system, self-centering latch pin, reinforced lid and high-strength body design as the crossovers. They mount on the top of the bed side walls and are ideal for storing longer tools and equipment. Innersides help keep the bed free for storing bulky items. Combine innersides with a crossover to create a wrap-around storage system.
