Peterbilt 375/377 Tool & Battery Boxes

Frequently Asked Questions About Peterbilt 375/377 Tool & Battery Boxes

Will these tool and battery boxes fit my Peterbilt 375 or 377 without modification?

Most tool and battery boxes designed for the Peterbilt 375/377 are built to match the factory mounting points and frame dimensions for these models. However, frame rail spacing and step or fuel tank configurations can vary depending on the truck's build year and options, so it's a good idea to check listed specifications and compare them to your truck's measurements before ordering.

What materials are these boxes made from, and how well do they hold up over time?

Tool and battery boxes for this category are typically constructed from aluminum or steel. Aluminum boxes resist rust and are lighter, making them a common choice for battery boxes, while steel options offer added durability for heavy tool storage. Look at the specific product description to confirm the material and any protective coating or finish, since this affects long-term resistance to road salt, moisture, and general wear.

Are these boxes designed to hold batteries specifically, or can they be used for tools too?

Some boxes in this category are built specifically for battery storage, with venting and mounting features suited to battery size and weight, while others are general-purpose tool boxes. Check the product title and description carefully, as battery boxes and tool boxes often have different internal dimensions, lid designs, and mounting hardware even if they look similar from the outside.

What's involved in installing a replacement tool or battery box?

Installation generally involves removing the old box, transferring or replacing mounting brackets, and securing the new box to the frame rail using bolts through the existing mounting holes. Most boxes are designed as direct bolt-on replacements, but you should have basic hand tools on hand and be prepared to make minor adjustments if your truck's mounting hardware has worn or been modified over time.

Do these boxes come with a lock, and how secure is the latch?

Many tool and battery boxes include a latch or paddle-style handle, and some are available with locking mechanisms while others require you to add your own padlock or aftermarket lock. If security is a priority, check the product listing for details on the latch type included and whether it accommodates a standard padlock.
