Store more tools, more easily.

We build the our big mouth step boxes to solve a problem. Traditional step box designs have small openings that can result in cumbersome access and can sometimes even limit the size of the items that you are able to store inside. We saw this as an opportunity to design our new Big Mouth step boxes boasting easier access, while still providing the security and functionality that our products are known for.

Our new big mouth step box design increases the size of the opening by approximately 50% making access less cumbersome and allowing larger sized items to fit into a smaller box.

Our Big Mouth Step Boxes are available in a number of different sizes and finishes to suit your taste and fit your truck. Standard big mouth step boxes available with smooth or checker plate aluminum doors. All boxes are made with strong, lightweight aluminum and are built to outlast your truck.
