Freightliner Century 112/120 Tool & Battery Boxes

Frequently Asked Questions About Freightliner Century 112/120 Tool & Battery Boxes

Will these tool and battery boxes fit my Freightliner Century 112 or 120 without modification?

These boxes are designed to match the mounting points and frame dimensions of the Century 112 and 120 models. However, because trucks can vary slightly due to prior modifications, aftermarket frame rails, or previous repairs, it's a good idea to compare the listed dimensions and mounting hole spacing against your truck before ordering. If you're unsure, our team can help confirm fitment based on your VIN or existing box measurements.

What material are these boxes made from, and how well do they hold up to the elements?

Most tool and battery boxes for the Century 112/120 are constructed from aluminum or steel, depending on the specific product. Aluminum options resist rust and are lighter, while steel boxes tend to offer more rigidity but require a protective finish to prevent corrosion. Check each product listing for the specific material and finish, such as polished, painted, or diamond plate, so you know what to expect in terms of appearance and long-term durability.

Can I install a tool or battery box myself, or do I need a professional?

Many of these boxes are designed for a bolt-on installation using the existing mounting brackets on your frame rail, which makes them manageable for someone comfortable with basic hand tools. That said, battery boxes may involve additional wiring or cable routing, so if you're not familiar with disconnecting and reconnecting battery cables safely, having a qualified technician handle the install is a smart choice.

Do these boxes come with mounting hardware and brackets included?

This varies by product, so always check the individual listing details before purchasing. Some boxes ship complete with brackets and hardware, while others are sold as the box only, assuming you're reusing your existing mounting components. If you're replacing a damaged box, it's worth confirming with us whether your current brackets are compatible with the replacement.

How do I know what size box I need, and can I get a bigger one than what came stock?

Tool and battery boxes are typically available in multiple lengths and depths to match different frame rail configurations and storage needs. If you're looking to upsize from your factory box, measure the available clearance on your frame rail, including nearby components like fuel tanks, exhaust, or air lines, to make sure a larger box won't interfere with anything. Our product pages list dimensions for each option so you can compare against your available space.
