Peterbilt 330/335/337 Tool & Battery Boxes

Frequently Asked Questions About Peterbilt 330/335/337 Tool & Battery Boxes

Will these tool and battery boxes fit my Peterbilt 330, 335, or 337 without modification?

Tool and battery boxes in this category are designed to match the frame rail spacing and mounting configurations commonly found on Peterbilt 330, 335, and 337 models. However, because trucks can vary by year, chassis setup, and prior aftermarket modifications, we recommend checking the listed specifications and measuring your frame rail width before ordering to confirm a proper fit.

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

These boxes are typically constructed from durable materials such as aluminum or steel, often finished with a diamond plate pattern for added strength and abrasion resistance. Aluminum options resist rust and are lighter in weight, while steel versions offer added durability at a higher weight. Both are built to withstand daily exposure to road grime, moisture, and temperature changes when properly maintained.

Can one box house both batteries and tools, or are they separate compartments?

Many boxes in this category are designed as combination units, with a dedicated battery compartment on one side and a separate lockable tool storage area on the other. Others are single-purpose, built strictly for battery mounting or strictly for tool storage. Be sure to check the product description to confirm the configuration before purchasing.

What tools or hardware do I need to install a replacement tool or battery box?

Most boxes mount using existing frame rail holes or brackets, so basic hand tools such as wrenches and a socket set are usually sufficient. Some installations may require drilling new mounting holes if your current bracket pattern differs from the replacement box. We recommend reviewing the installation notes on each product page and having a helper on hand, since these boxes can be heavy and awkward to position alone.

Do these boxes come with locks, and are the locks or keys replaceable?

Many tool and battery boxes include a integrated locking mechanism to help secure your tools and battery connections from theft or tampering. Lock and key styles vary by manufacturer, so if a lock is damaged or a key is lost, you will likely need to source a replacement from the same manufacturer or a compatible aftermarket lock kit. Check the product listing for details on the specific locking hardware included.
