Step Tool Boxes

Easily climb up and maximize storage.

HPI Semi Truck Step Tool Boxes are available in 12", 18", and 24" standard sizes, or any custom size you need. The boxes steps are forged with star-patterned safety decking to assure a solid footing and prevent accidents. Our lids open upward to give easy access to your cargo, not to mention we put a little kickstand that keeps the lid open. Other brands have drop lids that you have to reach over to get to your contents. That's not user friendly. Just another reason why Highway Products is built for the long haul with the actual user in mind!

  • 5052 Diamond Plate
    We build our Step Tool Boxes from diamond plate 5052 aluminum, the same material used by the military, aircraft manufactures and boat builders.
  • T Handle Locks
    Our ergonomically designed T-Handle locks are the most secure locking mechanism on the market.
  • Watertight Seal
    We use Clean Seal™ automotive stripping around the edges of each toolbox to ensure a watertight seal.
  • Piano Hinges
    Piano hinges provide full-length support and reduces stress points caused by inferior hinges.
  • Stainless Steel Torx Screws
    Stainless steel Torx screws are the toughest fasteners on the market today. These fasteners won't loosen as you drive down the road and a door can be replaced without a special rivet gun.
  • Easy Cargo Access
    The semi truck step's star-patterned safety decking assures sure footing and helps to prevent accidents. Our lids open upward to give easy access to your cargo. Plus, we put a little kickstand that keeps the lid open.
  • Designed For Safety
    The standard style step tool boxes make it hard to use without something to grab on to when you are going up and you have to back down the steps. Sometimes, the driver will elect to jump instead.This style allows the driver to walk up and down with ease.
