Peterbilt 389 Tool & Battery Boxes

Frequently Asked Questions About Peterbilt 389 Tool & Battery Boxes

Will these tool and battery boxes fit my Peterbilt 389 without modification?

Most tool and battery boxes in this category are designed to mount to the frame rails or existing mounting points on the Peterbilt 389, but fitment can vary depending on wheelbase, frame width, and whether your truck has factory mounting brackets already in place. Its important to check the listed dimensions and mounting specs for each product against your trucks measurements before ordering, and reach out to our team if youre unsure about compatibility.

What materials are these boxes made from, and how do they hold up to weather and road debris?

Boxes in this category are typically constructed from aluminum or steel, often with a diamond plate finish for added durability and a classic heavy-duty look. Aluminum options resist rust and are lighter weight, while steel tends to offer added strength but may require more attention to prevent corrosion over time. Either option is built to handle regular exposure to road grime, moisture, and temperature swings when properly installed and maintained.

Do these boxes come with mounting hardware, or do I need to buy that separately?

This varies by product and manufacturer. Some tool and battery boxes include mounting brackets and hardware, while others are sold as the box only, requiring separate purchase of brackets, bolts, or straps. Check the product description and included components list carefully, and if youre unsure, contact us before purchasing so you can order any additional hardware at the same time.

Can one box hold both batteries and tools, or are these separate products?

Some boxes are designed as combination units with separate compartments for batteries and tool storage, while others are dedicated solely to one purpose. If youre looking to consolidate battery and tool storage into a single unit, look for product titles and descriptions that specifically mention combo or dual-purpose designs, since not every box in this category is set up that way.

How difficult is installation, and can I do it myself?

Installation difficulty depends on the specific product and whether your truck already has mounting brackets in place. Many boxes bolt directly to existing frame mounts, making for a straightforward DIY installation with basic tools. However, if your truck lacks pre-existing mounting points, you may need to drill new holes or fabricate brackets, which could require more mechanical experience or a visit to a professional installer.
