This finish is ideal for truck owners who want long-lasting hardware that matches the vehicle's aesthetic without frequent upkeep.

Step Width: 6 inches

A 6-inch wide step provides a broad surface for your foot. This width offers a secure footing, reducing the chance of slipping when entering or exiting the truck.
