These aftermarket vehicle accessories are tubular or flat components installed along the sides of a truck, beneath the doors. Their primary function is to provide an intermediate stepping point for easier access into and out of the vehicle’s cabin, especially beneficial for taller trucks like a full-size pickup. They are typically constructed from materials like steel, aluminum, or composite polymers to withstand weight and environmental factors.
The benefits of these additions extend beyond mere convenience. They can also contribute to vehicle aesthetics, providing a rugged or customized appearance. Historically, such devices evolved from simple running boards designed for horse-drawn carriages and early automobiles. Modern iterations offer enhanced grip, corrosion resistance, and, in some cases, even protection against minor impacts from road debris or off-road obstacles.
