If you’ve been browsing truck accessories, especially for heavy-duty or vocational use, you may have come across the term saddle box — sometimes also called a step box or boot box. But what exactly is it, and why do so many drivers install them?
Let’s take a closer look.
A Saddle Box Is Storage and Access in One
A saddle box is a type of truck-mounted storage box designed to install between the drive axles of a Class 8 truck, typically mounted to the truck’s frame rail. Its defining feature is the integrated step, which allows drivers to safely climb onto the deck of the trailer or access mounted equipment behind the cab.
In other words, a saddle box combines:
- Secure storage for tools, chains, PPE, and other gear
- A safe, functional step for trailer or deck access
Because of this dual-purpose design, saddle boxes are also commonly called step boxes or boot boxes, especially in the heavy-duty market.

Step Box, Boot Box, or Saddle Box: What’s the Difference?

- Saddle Box – Most common term in product catalogs and technical specs
